feat(native-comp): no longer require gcc homebrew formula

Browse Source 
This finally makes Emacs.app with native-comp fully self-contained, no
longer requiring the GCC Homebrew formula to be installed when
loading *.eln files that link against
/usr/local/lib/gcc/11/libgcc_s.1.dylib.

By adding the signing entitlement
com.apple.security.cs.allow-dyld-environment-variables, which allows
dynamic library loading to be controlled via DYLD_* environment
variables. It seems the lack of this was preventing Emacs from loading
the bundled libgcc_s.1.dylib file from Contents/Frameworks.

Fixes #53
