The architectures provided to skipIf / expectedFail are regular
expressions (v. _match_decorator_property() in decorators.py
so on Darwin systems "arm64" would match the skips for "arm" (32-bit
Linux). Update these to "arm$" to prevent this, and also update
three tests (TestBuiltinFormats.py, TestCrossDSOTailCalls.py,
TestCrossObjectTailCalls.py) that were skipped for arm64 via this
behavior, and need to be skipped or they will fail.
This was moviated by the new TestDynamicValue.py test which has
an expected-fail for arm, but the test was passing on arm64 Darwin
resulting in failure for the CIs.

These handful of tests had a BOM (Byte order mark) at the beginning of
the file. This marker is unnecessary in our test files. The main
motivation for this is that the `ast` python module breaks when passing
a file to it with a BOM marker (and might break other tooling which
doesn't expect it). E.g.,:
```
"""Test that lldb command 'process signal SIGUSR1' to send a signal to the inferior works."""
^
SyntaxError: invalid non-printable character U+FEFF
```
If anyone is aware of a good reason to keep it, happy to drop this.

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.

This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).
If you end up having problems merging this commit because you have made
changes to a python file, the best way to handle that is to run `git
checkout --ours <yourfile>` and then reformat it with black.

Eliminate boilerplate of having each test manually assign to `mydir` by calling
`compute_mydir` in lldbtest.py.

and probably other posix oses. Use extra_images to ensure
LD_LIBRARY_PATH is set correctly.
Also take the opportunity to remove hand-rolled library extension
management code in favor of the existing one.

In general, it seems like the debugger should allow programs to load & run with
libraries as far as possible, instead of defaulting to being super-picky about
unavailable symbols.
This is critical on macOS/Darwin, as libswiftCore.dylib may 1) export a version
symbol using @available markup and then 2) expect that other exported APIs are
only dynamically used once the version symbol is checked. We can't open a
version of the library built with a bleeding-edge SDK on an older OS without
RTLD_LAXY (or pervasive/expensive @available markup added to dyld APIs).
This was previously committed as cb8c1ee269da and reverted due to
unknown failures on the Linux bots. This version adds additional asserts
to check that the shared objects are where we expect them & that calling
f1() from libt1 produces the expected value. The Linux failure is
tracked by https://bugs.llvm.org/show_bug.cgi?id=49656.

This reverts commit cb8c1ee269da72eb6e2c18800cd8ab0a74050785. The test
is failing on Debian for unknown reasons.
