Calling bootefi on an address that was loaded from memory (e.g., cramfs
or SPI flash via "sf read", etc.), currently results in the EFI binary
not being able to access the EFI image device path.
For example, iPXE would fail with an error "EFI could not get loaded
image's device path: Error 0x7f39e082 (https://ipxe.org/7f39e082)".
This is due to an incomplete special-case in efi_binary_run, where a new
device path was created but not used in all required places.
Fix the in-memory special case, set the "bootefi_device_path" to the
generated "file_path".
iPXE will now boot, and report the device path as
"/MemoryMapped(0x0,0xSTART,0xLEN)"

Add support to install an initrd when running an EFI binary

In preparation to support mutiple efi net udevices. Add a device path
cache to support device paths from multiple ethernet udevices.
The device paths can be added to the cache before EFI gets initialized and
the protocols get installed.

Rather than setting up the global variables and then making the call,
pass them into function directly. This cleans up the code and makes it
all a bit easier to understand.

This code is only needed if an invalid image/device path is passed in.
Move the code out to a caller where this can be dealt with. The normal
flow will provide these parameters.

This uses a few global variables at present. With the bootflow we have
the required parameters, so add a function which accepts these. Update
the existing function to call the new one with the globals.

Move this code into a function so it can be called from elsewhere.
Note that the recently added network code uses the same
'global variable' approach. It could use a separate clean-up.

Set the device path of the efi boot device to an HTTP device path
(as formed by efi_dp_from_http) when the next boot stage is loaded
using wget (i.e., when wget is used with wget_info.set_bootdev=1).
When loaded from HTTP, the device path should account for it so that
the next boot stage is aware (e.g. grub only loads its http stack if
it itself was loaded from http, and it checks this from its device path).

All call sites are using size rather than end addresses,
so instead - as previously done - calculating an end address
everywhere, just modify the function to use size and internally
calculate the end address

Some code moved from cmd/bootefi.c is actually necessary only for "bootefi

The code will never been opted out as unused code by a compiler which
doesn't know how EFI boot manager is implemented. So introduce a new
configuration, CONFIG_EFI_BINARY_EXEC, to enforce them opted out
