include/efi: Include BMP and BLT header macro definitions
This patch adds BMP image header and BLT header macros in
`efi_datatype.h` to implement a converter inside coreboot FSP 2.0
driver that converts any input *.BMP image into the BLT buffer.
The output BLT buffer is used by FSP-S to render any pre-boot display.
Added `Bmp.h` and `GraphicsOutput.h` files for `UDK base >= 2017`,
as these files were added with the UDK version 2017.
Note: BLT in UEFI BMP implementation stands for `Bit-block transfer`.
It is a method of copying graphis data (specifically images and fonts)
from one location to another (framebuffer), where the data is stored
in blocks of bits.
BUG=b:284799726
