Add a number of debug logs to the tpm module. The condition tag
for opening debugging is "tpm". On TPM machines, this will bring
great convenience to diagnosis and debugging.

Although the tpm_execute() series of functions are defined they are not
used anywhere. Several structures in the include/grub/efi/tpm.h header
file are not used too. There is even nonexistent grub_tpm_init()
declaration in this header. Delete all that unneeded stuff.
If somebody needs the functionality implemented in the dropped code then
he/she can re-add it later. Now it needlessly increases the GRUB
code/image size.

Like the tpm the shim_lock module is only enabled for x86_64 target.
However, there's nothing specific to x86_64 in the implementation and
it can be enabled for all EFI architectures.

grub_tpm_log_event() and grub_tpm_measure() are two functions that
have the same effect. So, keep grub_tpm_log_event() and rename it
to grub_tpm_measure(). This way we get also a more clear semantics.

Like grub_verifiers_open(), the grub_verify_string() should also
display this debug message, which is very helpful for debugging.
