[LLDB] Set and verify paths of properties from tablegen (#179524)
In #168245, I attempted to dump the available settings to Markdown. That
required a full build of LLDB. However, to build the docs, only the swig
wrappers should need to be compiled. The comment was that we should be
able to use the definitions from the TableGen files.

Currently, the property definitions in don't have information about the
path where they will be available. They only contain a `Definition`
which groups properties, so they can be added to
`OptionValueProperties`.

With this PR, I'm adding the path for each property definition. For
example, `symbols.enable-external-lookup` would have `Name =
enable-external-lookup, Path = symbols`. In LLDB itself, we don't need
this path, we only need it for the documentation. To avoid mismatches
between the actual path and the declared one, I added a debug-only check
when a property group is added to a parent
(`OptionValueProperties::AppendProperty`).

The TableGen emitter for the properties now additionally emits
`g_{definition}_properties_def`, which includes both the array of
properties and the expected path. This constant has to be used to
initialize a `OptionValueProperties`.

I couldn't test this for everything (e.g. IntelPT or ProcessKDP), but
the necessary changes are simple: (1) set the `Path` in the TableGen
file, (2) update `initialize` to use `_def`.

3c867898c7 [lldb] Add setting to override PE/COFF ABI by module name
The setting `plugin.object-file.pe-coff.module-abi` is a string-to-enum
map that allows specifying an ABI to a module name. For example:

    ucrtbase.dll=msvc
    libstdc++-6.dll=gnu

This allows for debugging a process which mixes both modules built using
the MSVC ABI and modules built using the MinGW ABI.

Depends on D127048

25c8a061c5 [lldb] Set COFF module ABI from default triple and make it an option
PE/COFF can use either MSVC or GNU (MinGW) ABI for C++ code, however
LLDB had defaulted to MSVC implicitly with no way to override it. This
causes issues when debugging modules built with the GNU ABI, sometimes
even crashes.

This changes the PE/COFF plugin to set the module triple according to
the default target triple used to build LLDB. If the default target
triple is Windows and a valid environment is specified, then this
environment will be used for the module spec. This not only works for
MSVC and GNU, but also other environments.

A new setting, `plugin.object-file.pe-coff.abi`,  has been added to
allow overriding this default ABI.
