ci: fix pullapprove incorrectly skipping fw-compiler as owner (#36661)

Currently, if changes are made to `compiler-cli/ngcc` and to other
compiler-related files, then only the `fw-ngcc` group is requested
for review. This is because the `not contains_any_globs` condition
will be false for `fw-compiler` and the group will never become active.

We fix this by removing the incorrect condition and filtering out ngcc
files before checking `contains_any_globs` in the primary fw-compiler
condition.
