MdeModulePkg/BootGraphicsResourceTableDxe: Use BmpSupportLib
https://bugzilla.tianocore.org/show_bug.cgi?id=800 Based on content from the following branch/commits: https://github.com/Microsoft/MS_UEFI/tree/share/MsCapsuleSupport33bab4031aca516b1a612b9f111f2eUse BmpSupportLib to convert a GOP BLT Buffer to the BMP graphics image that is published in an ACPI BGRT table. * Remove use of IndustryStandard/Bmp.h include file * Remove mBmpImageHeaderTemplate. This is handled by BmpSupportLib * Clean up code style with function prototypes at top and all module global variables together * Update SetBootLogo() to use SafeIntLib to check input parameters for overflows. * Remove internal function BgrtAcpiTableChecksum(). Use CalculateCheckSum8() directly from BgrtReadyToBootEventNotify() * Remove InstallBootGraphicsResourceTable(). Move all the code into BgrtReadyToBootEventNotify() that is signaled at ready to boot. * Remove all logic that converts a GOP BLT buffer to a BMP graphics image and use BmpSupportLib function TranslateGopBltToBmp() instead. * Use AllocatePool() instead of AllocatePages() to allocate copy of BMP image that is provided by BGRT. This is required to be compatible with BmpSupportLib function TranslateGopBltToBmp() that uses AllocatePool(). * Zero OemId in BGRT header before filling in value from PCD. * Get size of PcdAcpiDefaultOemId and only copy the the size of the PCD if it is smaller than the size of the OemId field in the BGRT header. * Use WriteUnaligned24() instead of CopyMem() for the OemTableId field of the BGRT header.
