[LLDB] Add missing declarations for linking to psapi

[mstorsjo]

Summary

This fixes building for mingw with BUILD_SHARED_LIBS. In static builds, the psapi dependency gets linked in transitively from Support, but when linking Support dynamically, it's revealed that these components also need linking against psapi.

I guess this is causing the windows failure on the bot: http://lab.llvm.org:8011/builders/lldb-x64-windows-ninja/builds/13320

Yeah, I saw that - highly strange. I'll try to see if I can reproduce similar issues with a similar toolchain, and I'll push a revert soon unless I find some great clue.

Seems like this was nondeterministic? http://lab.llvm.org:8011/builders/lldb-x64-windows-ninja/builds/13321 Maybe a dependency issue on the tblgen.exe...

The issue seems to have vanished in the following build, http://lab.llvm.org:8011/builders/lldb-x64-windows-ninja/builds/13321, and I built a lldb-tblgen.exe using a fairly new version of MSVC, and that didn't seem to have the same issue ("This version of lldb-tblgen.exe is not compatible with the version of Windows you're running."). And the changes I pushed here shouldn't even affect the build of lldb-tblgen.exe at all. So I'd consider this just a coincidence/fluke for now.
