Recommit: [lldb] Remove "dwarf dynamic register size expressions" from RegisterInfo

The previous version of the patch did not update the definitions in
conditionally compiled code. This patch includes changes to ARC and
windows targets.

Original commit message was:

These were added to support some mips registers on linux, but linux mips
support has now been removed due.

They are still referenced in the freebds mips implementation, but the
completeness of that implementation is also unknown. All other
architectures just set these fields to zero, which is a cause of
significant bloat in our register info definitions.

Arm also has registers with variable sizes, but they were implemented in
a more gdb-compatible fashion and don't use this feature.

Make offset field optional in RegisterInfo packet for Arm64

This patch carries forward our aim to remove offset field from qRegisterInfo
packets and XML register description. I have created a new function which
returns if offset fields are dynamic meaning client can calculate offset on
its own based on register number sequence and register size. For now this
function only returns true for NativeRegisterContextLinux_arm64 but we can
test this for other architectures and make it standard later.

As a consequence we do not send offset field from lldb-server (arm64 for now)
while other stubs dont have an offset field so it wont effect them for now.
On the client side we have replaced previous offset calculation algorithm
with a new scheme, where we sort all primary registers in increasing
order of remote regnum and then calculate offset incrementally.

This committ also includes a test to verify all of above functionality
on Arm64.

[lldb][NFC] Fix all formatting errors in .cpp file headers

Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).

This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

[lldb] NFC modernize codebase with modernize-use-nullptr

Summary:
NFC = [[ https://llvm.org/docs/Lexicon.html#nfc | Non functional change ]]

This commit is the result of modernizing the LLDB codebase by using
`nullptr` instread of `0` or `NULL`. See
https://clang.llvm.org/extra/clang-tidy/checks/modernize-use-nullptr.html
for more information.

This is the command I ran and I to fix and format the code base:

```
run-clang-tidy.py \
-header-filter='.*' \
-checks='-*,modernize-use-nullptr' \
-fix ~/dev/llvm-project/lldb/.* \
-format \
-style LLVM \
-p ~/llvm-builds/debug-ninja-gcc
```

NOTE: There were also changes to `llvm/utils/unittest` but I did not
include them because I felt that maybe this library shall be updated in
isolation somehow.

NOTE: I know this is a rather large commit but it is a nobrainer in most
parts.

Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Move Args.cpp from Interpreter to Utility

Summary:
The Args class is used in plenty of places besides the command
interpreter (e.g., anything requiring an argc+argv combo, such as when
launching a process), so it needs to be in a lower layer. Now that the
class has no external dependencies, it can be moved down to the Utility
module.

This removes the last (direct) dependency from the Host module to
Interpreter, so I remove the Interpreter module from Host's dependency
list.

Fix TestStopReplyContainsThreadPcs on 32-bit x86 (pr36013)

Summary:
The issue was that we were parsing the registers into 64-bit integers
and the calling swapByteOrder without regard for the actual size of the
register. This switches the test to use the RegisterValue class which
tracks the register size, and knows how to initialize itself from a
piece of memory (so we don't need to swap byte order ourselves).

Summary:
Right now the test client is not parsing register values correctly,
which is manifesting itself in one test failing on 32-bit architectures

and stores it in the client, which will enable fixing the parsing in a
follow up commit.

to send a message get a parsed response in a single call.

lldb-server tests: Add support for testing debugserver

Summary:
This adds support for running the lldb-server test suite (currently consisting
of only one test) against the debugserver. Currently, the choice which binary
to test is based on the host system. This will need to be replaced by something
more elaborate if/when lldb-server starts supporting debugging on darwin.

I need to make a couple of tweaks to the test client to work with debugserver:
- debugserver has different command-line arguments - launching code adjusted to
handle that
- debugserver sends duplicate "medata" fields in the stop reply packet -
adjusted stop-reply parsing code to handle that
- debugserver replies to the k packet instead of just dropping the connection -
stopping code adjusted, although we should probably consider aligning the
behavior of the two stubs in this case
