Exclude more rarely-used stuff from Windows headers (#8513)

This PR defines a series of `NOSOMETHING` macros in PCHs, in order to
prevent `windows.h` from bringing a lot of rarely used things into the
project. 

Theoretically this should make PCH generation and overall complication
faster, but I didn't really benchmark the speed. 

Another benefit would be reducing the symbol noises caused by
`windows.h`.
