Remove usage of MemoryAllocationLib, and use a simplistic allocation
routine which makes use of the decompression scratch buffer.

This resolves a potential issue where the usage of the LZMA library
in the PEI phase may not have enough memory for the AllocatePool
function call.  (Some platforms may be extremely constrained in
heap space for the PEI phase.)
