Add PY_CORE_EXE_LDFLAGS and EXE_LDFLAGS which stores executable specific LDFLAGS, replacing PY_CORE_LDFLAGS for building executable targets. If PY_CORE_EXE_LDFLAGS / EXE_LDFLAGS is not provided, then it defaults to the value of PY_CORE_LDFLAGS which is the existing behaviour. If both flags are supplied, and there is a need to distinguish between executable and shared specific LDFLAGS, in particular, PY_CORE_LDFLAGS should contain the shared specific LDFLAGS.

Introduce two new flags
EXE_LDFLAGSandPY_CORE_EXE_LDFLAGSto contain executable target specific linker options for building the python interpreter as well as other executables.Notes
If provided, this effectively means that
PY_CORE_LDFLAGS(as well as the chain of flags used by this variable) is exclusively used to build shared libraries / bundles. In addition, any common linker flags applicable to both types of targets would also need to be supplied toEXE_LDFLAGSandLDFLAGS.📚 Documentation preview 📚: https://cpython-previews--137296.org.readthedocs.build/
