After 9611282c, TestGdbRemoteThreadsInStopReply is not non-deterministic

[lldb] Adjust windows xfails for D119167

A couple of additional tests pass with that patch. One new test fails
(because it's not testing a slightly different thing). I'll update it
later to restore the original meaning (I don't want to revert as the net
effect is still very positive), but for now this gets the bot green.

[lldb/test] Remove sleeps from some lldb-server tests

Instead of using sleeps, have the inferior notify us (via a trap opcode) that
the requested number of threads have been created.

This allows us to get rid of some fairly dodgy test utility code --
wait_for_thread_count seemed like it was waiting for the threads to
appear, but it never actually let the inferior run, so it only succeeded
if the threads were already started when the function was called. Since
the function was called after a fairly small delay (1s, usually), this
is probably the reason why the tests were failing on some bots.

[lldb/test] Automatically skip remote lldb-server tests when applicable

The tests don't work with remote debugservers. This isn't a problem with
any particular test, but the test infrastructure itself, which is why
each of these tests has a @skipIfDarwinEmbedded decorator.

This patch replaces that with a central category-based solution. It also
moves the ad-hoc windows skipping mechanism there too.

[lldb/test] Reduce boilerplate in lldb-server tests

Nearly all of our lldb-server tests have two flavours (lldb-server and
debugserver). Each of them is tagged with an appropriate decorator, and
each of them starts with a call to a matching "init" method. The init
calls are mandatory, and it's not possible to meaningfully combine them
with a different decorator.

This patch leverages the existing decorators to also tag the tests with
the appropriate debug server tag, similar to how we do with debug info
flavours. This allows us to make the "init" calls from inside the common
setUp method.

[lldb-server] jThreadsInfo returns stack memory

This patch adds parts of the stack that should be useful for unwinding
to the jThreadsInfo reply from lldb-server. We return the top of the
stack (12 words), and we also try to walk the frame pointer linked list
and return the memory containing frame pointer and return address pairs.
The idea is to cover the cases with and without frame pointer omission.

[lldb] Replace assertTrue(a == b, "msg") with assertEquals(a, b, "msg") in the test suite

Summary:
The error message from the construct `assertTrue(a == b, "msg") ` are nearly always completely useless for actually debugging the issue.
This patch is just replacing this construct (and similar ones like `assertTrue(a != b, ...)` with the proper call to assertEqual or assertNotEquals.

This patch was mostly written by a shell script with some manual verification afterwards:
```
lang=python
import sys

def sanitize_line(line):
if line.strip().startswith("self.assertTrue(") and " == " in line:
line = line.replace("self.assertTrue(", "self.assertEquals(")
line = line.replace(" == ", ", ", 1)
if line.strip().startswith("self.assertTrue(") and " != " in line:
line = line.replace("self.assertTrue(", "self.assertNotEqual(")
line = line.replace(" != ", ", ", 1)
return line

for a in sys.argv[1:]:
with open(a, "r") as f:
lines = f.readlines()
with open(a, "w") as f:
for line in lines:
f.write(sanitize_line(line))
```
