efi/tpm: Remove unused functions and structures

Browse source 
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.
