efi_loader: Cleanup UEFI Variables menu selection

Browse Source 
There are 3 options listed between choice/endchoice FILE/TEE/NO_STORE.
There is no reason to add other config with dependencies between
choice/endchoice because they can never be selected because they depends on
only that 3 options which can be selected.
That's why move additional configuration with dependency below choice
section.

When EFI variables are stored on file we don't allow SetVariableRT,

we copy runtime variables in DRAM and support GetVariableRT

the RAM contents to the file, otherwise any changes made during
runtime won't persist reboots.
