EmbeddedPkg: get rid of BdsLib dependency from Android*Boot

EmbeddedPkg: get rid of BdsLib dependency from Android*Boot

The sum use these applications made of BdsLib was one invocation of the
IS_DEVICE_PATH_NODE macro, and (incorrectly) being able to leave out a
dependency on gEfiLoadedImageProtocolGuid.

So expand the macro in place and add the missing dependency.
Then clean up the .dsc, .inf and #includes accordingly.
