[lldb] Add SBThread.selected_frame property (#123981)

Adds a `selected_frame` property to `SBThread`. The setter accepts either a frame index (like `SetSelectedFrame`), or a frame object.

Updates a few tests to make use of the new `selected_frame`. While doing so I noticed some of the usage could be cleaned up, so I did that too.

[lldb][test][NFC] Remove BOM characters from tests (#97045)

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.

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

LocationListLookup test case failing on lldb-arm-ubuntu

Skip on linux+arm for now until I can try to repo the setup of the
lldb-arm-ubuntu bot. The name of the binary in argv[0] was not
able to be retrieved here; if the compiler's codegen had it stored
in a caller saved register, because it's not needed at this point,
it may not be retreivable.

Decr pc when looking for DWARF loc list entry mid-stack

When looking for a variable location in a DWARF location list,
we search the list of ranges to find one that includes the pc.
With a function mid-stack, the "pc" is the return pc instead of
the call instruction, and in optimized code this can be another
function or a different basic block (with different variable
locations). Back up the "pc" value mid-stack to find the correct
location list entry.
