Ard Biesheuvel 44e6186eea EmbeddedPkg/FdtLib: incorporate missing overlay support
Commit a099239015 ("EmbeddedPkg/FdtLib: Update FdtLib to v1.4.5")
updated our FdtLib implementation to a more recent upstream version,
but omitted fdt_overlay.c due to its ambiguous licensing situation.
This has been resolved now, so take the latest upstream version of
the file (which received no other modifications in the mean time)
and add it to FdtLib.

Note that fdt_overlay.c has a dependency on strtoul() which EDK does
not provide natively, so add a private implementation that wraps the
BaseLib routines that do roughly the same.

Michael Zimmermann 84513df419 EmbeddedPkg/FdtLib: build fdt_empty_tree.c
We're currently building everything except for this file.
Since 'fdt_create_empty_tree' can be useful for some
platforms, compile this one too.

Ard Biesheuvel 1e9b2bddff EmbeddedPkg: Split off FDT loading functionality from FdtLib
Split off the recently added functionality to load device tree images and
install them as configuration tables, as it introduces a dependency on
UefiBootServicesTableLib, preventing FdtLib from being used during SEC and
PEI phases.
