2405: BaseTools/MuCodeQlQueries.qls: Removed unused static function q…

…uery (#1067)

## Description

This is the Project Mu equivalent of the following edk2 commit:

`1bb9f47`

This commit can be squashed with the commit that adds
`MuCodeQlQueries.qls` in the future.

---

This query seems to produce a rate of false positives with some common
patterns in edk2 like passing function pointers for callback.

Due to the usage of `STATIC` instead of `static` particularly for
functions, this query was rarely used in the past. It is removed here to
prevent future false positives.

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

## How This Was Tested

- CodeQL with a `static` function present in the code

## Integration Instructions

- N/A
