Remove Python 2 checks from the test suite

We dropped downstream support for Python 2 in the previous release. Now
that we have branched for the next release the window where this kind of
change could introduce conflicts is closing too. Remove Python 2 checks
from the test suite.

[lldb] Replace asserts on .Success() with assertSuccess()

Replace forms of `assertTrue(err.Success())` with `assertSuccess(err)` (added in D82759).

* `assertSuccess` prints out the error's message
* `assertSuccess` expresses explicit higher level semantics, both to the reader and for test failure output
* `assertSuccess` seems not to be well known, using it where possible will help spread knowledge
* `assertSuccess` statements are more succinct

[lldb] Fix TestFileHandle.py

Fixed use of -o and -k in LLDB under Windows when statically compiled with vcruntime.

Right now if the LLDB is compiled under the windows with static vcruntime library, the -o and -k commands will not work.

The problem is that the LLDB create FILE* in lldb.exe and pass it to liblldb.dll which is an object from CRT.
Since the CRT is statically linked each of these module has its own copy of the CRT with it's own global state and the LLDB should not share CRT objects between them.

In this change I moved the logic of creating FILE* out of commands stream from Driver class to SBDebugger.
To do this I added new method: SBError SBDebugger::SetInputStream(SBStream &stream)

Command to build the LLDB:
cmake -G Ninja -DLLVM_ENABLE_PROJECTS="clang;lldb;libcxx" -DLLVM_USE_CRT_RELEASE="MT" -DLLVM_USE_CRT_MINSIZEREL="MT" -DLLVM_USE_CRT_RELWITHDEBINFO="MT" -DP
YTHON_HOME:FILEPATH=C:/Python38 -DCMAKE_C_COMPILER:STRING=cl.exe -DCMAKE_CXX_COMPILER:STRING=cl.exe ../llvm

Command which will fail:
lldb.exe -o help

[lldb][testsuite] Create a SBDebugger instance for each test

Some tests set settings and don't clean them up, this leads to side effects in other tests.
The patch removes a global debugger instance with a per-test debugger to avoid such effects.

From what I see, lldb.DBG was needed to determine the platform before a test is run,
lldb.selected_platform is used for this purpose now. Though, this required adding a new function
to the SBPlatform interface.
