[lldb] Register 'target modules dump pcm-info' from TypeSystemClang (#229816)
`ModuleListProperties` calls
`clang::driver::Driver::getDefaultModuleCachePath`, so `lldbCore` links
`clangDriver`, which drags in `clangAST` and most of LLVM via static
initializers.
Set the default from `TypeSystemClang::Initialize` instead. Every tool
that uses the clang module cache registers `TypeSystemClang`.
Combined with https://github.com/llvm/llvm-project/pull/229817, this
halves the size of the lldb-server.exe binary on Windows.
