[NFC][Py Reformat] Reformat python files in lldb
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.

cb0eb9d8dd [test] Fix LLDB tests with just-built libcxx when using a target directory.
In certain configurations, libc++ headers all exist in the same directory, and libc++ binaries exist in the same directory as lldb libs. When `LLVM_ENABLE_PER_TARGET_RUNTIME_DIR` is enabled (*and* the host is not Apple, which is why I assume this wasn't caught by others?), this is not the case: most headers will exist in the usual `include/c++/v1` directory, but `__config_site` exists in `include/$TRIPLE/c++/v1`. Likewise, the libc++.so binary exists in `lib/$TRIPLE/`, not `lib/` (where LLDB libraries reside).

This also adds the just-built-libcxx functionality to the lldb-dotest tool.

The `LIBCXX_` cmake config is borrowed from `libcxx/CMakeLists.txt`. I could not figure out a way to share the cmake config; ideally we would reuse the same config instead of copy/paste.

4763200ec9 Add the ability to show when variables fails to be available when debug info is valid.
Summary:
Many times when debugging variables might not be available even though a user can successfully set breakpoints and stops somewhere. Letting the user know will help users fix these kinds of issues and have a better debugging experience.

Examples of this include:
- enabling -gline-tables-only and being able to set file and line breakpoints and yet see no variables
- unable to open object file for DWARF in .o file debugging for darwin targets due to modification time mismatch or not being able to locate the N_OSO file.

This patch adds an new API to SBValueList:

  lldb::SBError lldb::SBValueList::GetError();

object so that if you request a stack frame's variables using SBValueList SBFrame::GetVariables(...), you can get an error the describes why the variables were not available.

This patch adds the ability to get an error back when requesting variables from a lldb_private::StackFrame when calling GetVariableList.

It also now shows an error in response to "frame variable" if we have debug info and are unable to get varialbes due to an error as mentioned above:

(lldb) frame variable
error: "a.o" object from the "/tmp/libfoo.a" archive: either the .o file doesn't exist in the archive or the modification time (0x63111541) of the .o file doesn't match

d68ebea767 Reland [lldb] Explicitly use the configuration architecture when building test executables
This originally broke the TestQuoting which explicitly called buildDefault
instead of calling build() and marking the test as no_debug_info_test.
TestQuoting has been rewritten by now and is using `build`, so this should now
pass on all platforms.

Original summary:

The Darwin builder currently assumes in `getArchCFlags` that the passed `arch`
value is an actual string it can string.join with vendor/os/version/env strings:

```
   triple = '-'.join([arch, vendor, os, version, env])
```

However this is not true for most tests as we just pass down the `arch=None`
default value from `TestBase.build`. This causes that if we actually end up in
this function we just error out when concatenating `None` with the other actual
strings of vendor/os/version/env. What we should do instead is check that if
there is no test-specific architecture that we fall back to the configuration's
architecture value.

It seems we already worked around this in `builder.getArchSpec` by explicitly
falling back to the architecture specified in the configuration.

This patch just moves this fallback logic to the top `build` function so that it
affects all functions called from `TestBase.build`.

dfc7243952 [lldb] Don't add no-sandbox entitlement when running tests on simulator
It seems that if codesigning the test executables with the
`com.apple.private.security.no-sandbox` entitlement then the simulator refuses
to launch them and every test fails with `Process launch failed: process exited
with status -1 (no such process.)`.

This patch checks if we're trying to run the test suite on the simulator and
then avoids signing the executable with `no-sandbox`.
