BMP files by tools other than MS paint can have a
variable number of padding bytes, which results in
the DataSize being less than (ImageSize - HeaderSize).
Fix the check to be less stringent.
Test: use BMP created by/saved by Photoshop

The patch adds check logic to make sure that for a input BMP file,
the width or height is not 0; for a input GOP blt buffer, the width
or height is not 0. Otherwise, UNSUPPORTED status is returned.

Since the pointer subtraction here is not performed by pointers to
elements of the same array object. This might lead to potential issues,
such behavior is undefined according to C11 standard.
Refine the pointer subtraction expressions by casting each pointer to
UINTN first and then perform the subtraction.
