tpm: Avoid code bloat when not using EFI_TCG2_PROTOCOL
It does not make sense to enable all SHA algorithms unless they are
needed. It bloats the code and in this case, causes chromebook_link to
fail to build. That board does use the TPM, but not with measured boot,
nor EFI.
Since EFI_TCG2_PROTOCOL already selects these options, we just need to
add them to MEASURED_BOOT as well.
Note that the original commit combines refactoring and new features,
which makes it hard to see what is going on.
