[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.
