ArmPkg: Remove BasePeCoffLib

ArmPkg contains unused and outdated code for runtime PE/COFF image
relocation.

- Use the version in MdePkg instead.
- Remove references to this package from BeagleBoardPkg.

ArmPkg/BasePeCoffLib was added to deal with MOVT instruction that
was not part of the PE/COFF specification at that time.
