[do not merge] Combined TPM eventlog

[SergiiDmytruk]

Actual code changes are in EDK, coreboot only needs to not publish related ACPI entries.

~~Testing on APUs won't work without reverting modifications in src/drivers/pc80/tpm/tis.c which somehow disables a working TPM.~~

EDK PR: https://github.com/Dasharo/edk2/pull/139

This now also includes picking TCG log format at runtime.
