[lldb][test] Modernize asserts (#82503)

This uses [teyit](https://pypi.org/project/teyit/) to modernize asserts,
as recommended by the [unittest release
notes](https://docs.python.org/3.12/whatsnew/3.12.html#id3).

For example, `assertTrue(a == b)` is replaced with `assertEqual(a, b)`.
This produces better error messages, e.g. `error: unexpectedly found 1
and 2 to be different` instead of `error: False`.

[lldb] Replace assertEquals with assertEqual (NFC) (#82073)

assertEquals is a deprecated alias for assertEqual and has been removed
in Python 3.12. This wasn't an issue previously because we used a
vendored version of the unittest module. Now that we use the built-in
version this gets updated together with the Python version used to run
the test suite.

[lldb-server] Report launch error in vRun packets

Uses our existing "error string" extension to provide a better
indication of why the launch failed (the client does not make use of the
error yet).

[lldb-server] Report launch error in vRun packets

Uses our existing "error string" extension to provide a better
indication of why the launch failed (the client does not make use of the
error yet).

Also, fix the way we obtain the launch error message (make sure we read
the whole message, and skip trailing garbage), and reduce the size of
TestLldbGdbServer by splitting some tests into a separate file.

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.
