[InstrProf][attempt 2] Add new format for -fprofile-list=

In D130807 we added the `skipprofile` attribute. This commit
changes the format so we can either `forbid` or `skip` profiling
functions by adding the `noprofile` or `skipprofile` attributes,
respectively. The behavior of the original format remains
unchanged.

Also, add the `skipprofile` attribute when using
`-fprofile-function-groups`.

This was originally landed as https://reviews.llvm.org/D130808 but was
reverted due to a Windows test failure.
