cr50: set compiler options to ensure reproducible FIPS module
As per b/277777628 FIPS module build depends on value of `CC` env var,
which is not a desirable behavior.
1. Add -fconserve-stack to FIPS module builds explicitly to make sure
its digest is same as reported and doesn't depend on environment.
2. gcc specific option moved to core/cortex-m/build.mk
3. Verified that binutils workaround is still needed (b/238039591)
BUG=b:277777628, b:238039591
TEST=make BOARD=cr50; tpm_test.py, FIPS digest is the same
