[Github]Update PGO with more filepaths (#93720)

- `llvm/**/ProfileData/**/*` intends to cover `llvm/include/llvm/ProfileData/` and `llvm/lib/ProfileData/`
- `llvm/**/SampleProfile*` intends to cover a bunch of SamplePGO files and their headers. For example, 
    `SampleProfile.cpp`, `SampleProfileMatcher.cpp`, `SampleProfileProbe.cpp`
- `llvm/**/CodeGen/MIRSampleProfile*` intends to cover MIRSampleProfile.cpp and its header.
- `llvm/test/Transforms/SampleProfile/**/*` intends to cover unit tests.
