Use separate PDB files for compiling and linking in MSVC builds

Browse Source 
The two PDB files that the MSVC compiler and linker create are supposed
to be handled differently and should not share the same file path.
Using the same file path for both can result in corrupted PDB files and
longer build times.

Use $${TARGET}.vc.pdb in the OBJECTS_DIR for the compiler and
$${TARGET}.pdb (the default) for the linker.
