san7890andGitHub 018c10f9a0 Fixes Define Sanity (#77845)
## About The Pull Request

Hey there,

This was broken in an update from #74573
(3902973978), the RegEx was only catching
a fraction of the cases it was meant to be.

This is what we were finding on 74573 version of the RegEx:

This is what we should be finding for all of the cases that
`define_sanity` will need to check for:

This is what was broken as a consequence:

As stated in the introductory PR #74333
(ccef887efe), it's not the end of the
world if we miss unmanaged local defines, but it's still useful to have
this as a maintainability tool to ensure that everything remains as
clean as it possibly can. I wish we could do the whole matching method
like the aforementioned PR supposed could happen, but it simply doesn't
appear to work the way we want it to.

## Changelog
Nothing player facing.

I tried to experiment with `UNLINT()` but I got absolutely ganked by
getting the regex to work, so the fix for the FA Icon file may not be
super duper great unfortunately. Let me know if you have a showstopper
idea, this is just a stopguard so this PR can get merged and I don't
have to keep talking about unmanaged local defines while reviewing PRs.
