7017fc54a5 bootmeth: use efi_loader interfaces instead of bootefi command
Now that efi_loader subsystem provides interfaces that are equivalent
with bootefi command, we can replace command invocations with APIs.

eb09c33084 bootstd: Fix a memory leak in the efi manager bootflow
efi_get_var() allocates memory which has to be freed after the value of
the variable is consumed. Free the memory properly

Enable the bootflow based on this bootmeth if the BootOrder EFI
variable is set.

865328c314 bootstd: Rename bootdev checkers
These functions return 0 if the check passes, so the names are somewhat
confusing. Rename them.

2662b54d70 bootstd: Allow EFI bootmgr to support an invalid bootflow
For most testing we don't want this bootmeth to actually do anything. For
the one test where we do, add a test hook to obtain the correct behaviour.
This will allow us to bind the device always, rather than just doing it
for this test.

bc06aa035d bootstd: Allow bootmeths to be marked as global
The current way of handling things like EFI bootmgr is a bit odd, since
that bootmeth handles selection of the bootdev itself. VBE needs to work
the same way, so we should support it properly.

Add a flag that indicates that the bootmeth is global, rather than being
invoked on each bootdev. Provide a helper to read a bootflow from the
bootmeth.

0b41525e8f bootstd: Add an implementation of EFI bootmgr
Add a bootmeth driver which handles EFI boot manager, using EFI_LOADER.

In effect, this provides the same functionality as the 'bootefi bootmgr'
command and shares the same code. But the interface into it is via a
bootmeth, so it does not require any special scripts, etc.

For now this requires the 'bootefi' command be enabled. Future work may
tidy this up so that it can be used without CONFIG_CMDLINE being enabled.
