[SQUASH ON REBASE] Move inline comments to separate lines for tools_d…

…ef (#1190)

## Description

The existing change somehow will make the PP_FLAGS have `# MU_CHANGE`
embedded, causing the build to fail:

`"PP_FLAGS" : -E -x assembler-with-cpp -include AutoGen.h # MU_CHANGE
-I`

This change removed applicable inline comments. But the real change
should probably come from the parser.

- [x] Impacts functionality?
- [ ] Impacts security?
- [ ] Breaking change?
- [ ] Includes tests?
- [ ] Includes documentation?

## How This Was Tested

This change was tested on the failing system and this fixed it.

## Integration Instructions

N/A
