[efi] Defer autoboot link-layer address and autoexec script probing

The code to detect the autoboot link-layer address and to load the
autoexec script currently runs before the call to initialise() and so
has to function without a working heap.

This requirement can be relaxed by deferring this code to run via an
initialisation function.  This gives the code a normal runtime
environment, but still invokes it early enough to guarantee that the
original loaded image device handle has not yet been invalidated.
