sec/intel/txt: Allow skipping ACM NOP function
This is merely used to test whether the BIOS ACM calling code is working
properly. There's no need to do this on production platforms. Testing on
Haswell showed that running this NOP function breaks S3 resume with TXT.
Add a Kconfig bool to control whether the NOP function is to be invoked.
