Laszlo Ersek 8596c14090 MdePkg/BaseLib: add PatchInstructionX86()
Some edk2 modules generate X86 machine code at module execution time by:

- compiling "template" code with NASM at module build time,

- linking the object code into the module,

- and patching the immediate (constant) operands of some instructions when
  the module is executed.

Add a helper function to BaseLib so that the C code performing the
patching is easier to read and maintain.

The implementation in this patch is taken mainly from Mike Kinney's
mailing list messages at
