MdePkg/BasePeCoffLib: Add more check for relocation data

MdePkg/BasePeCoffLib: Add more check for relocation data

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1426

V2:
(1) Add NULL pointer check for the input parameters
(2) Add check for the "Adjust" value before applying fix ups.

In function PeCoffLoaderRelocateImageForRuntime, it doesn't
do much check when do relocation. For API level consideration,
it's not safe enough.
So this patch is to replace the same code logic with function
PeCoffLoaderImageAddress which will cover more validation.
