[FREELDR][HACK] Temporarily disable registry recovery code for AMD64

The newly implemented code for registry recovery makes the FreeLdr binary to grow
in size, to the point that it would BSOD because the PE image is too big.

For now we have to temporarily disable any of the newly added code, until
either FreeLdr is split into a basic PE bootloader image itself and a
"FreeLdrlib" that is used by the PE image to access various bootloader APIs
or another proper solution is found.
