Ard Biesheuvel fcf41edf2f EmbeddedPkg/AndroidFastbootApp: remove dependency on deprecated BdsLib
One of the last remaining modules with a dependency on the deprecated
BdsLib implementation from ArmPkg is the Android fastboot application.

Its only dependency on BdsLib is BdsStartEfiApplication(), which is
used in the most peculiar way: the fastboot app loads the kernel image
into memory, and creates a MemoryMapped() device path for it. It then
proceeds and calls BdsStartEfiApplication(), which explicitly loads the
contents of the devicepath into memory, creating a second in-memory copy
of the kernel image, after which it invokes gBS->LoadImage() with a
buffer address and size (while it is perfectly capable of loading from
a devicepath directly)

Since we know the device path is fully qualified and connected, and does
not require any of the additional processing that BdsStartEfiApplication()
does when dereferencing a device path, we should be able to pass this
devicepath into LoadImage() directly.

So create a simplified local clone of BdsStartEfiApplication(), and drop
the dependency on BdsLib.
