[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
