Update the PCBuild8 solution.

Facilitate cross-compilation by having binaries in separate Win32 and x64 directories.
Rationalized configs by making proper use of platforms/configurations.
Remove pythoncore_pgo project.
Add new PGIRelease and PGORelease configurations to perform Profile Guided Optimisation.
Removed I64 support, but this can be easily added by copying the x64 platform settings.
