efi_loader: Force a single FMP instance per hardware store
Chapter 23 of the EFI spec (rev 2.9) says:
"A specific updatable hardware firmware store must be represented by
exactly one FMP instance".
This is not the case for us, since both of our FMP protocols can be
installed at the same time because they are controlled by a single
'dfu_alt_info' env variable.
So make the config options depend on each other and allow the user to
install one of them at any given time. If we fix the meta-data provided
by the 'dfu_alt_info' in the future, to hint about the capsule type
(fit or raw) we can revise this and enable both FMPs to be installed, as
long as they target different firmware hardware stores
Note that we are not using a Kconfig 'choice' on purpose, since we
want to allow both of those to be installed and tested in sandbox
