/**
Insyde multi board image package extension.
This is the "MAIN" function for parsing multi-image package.
Input a image package(multi), output a image package(single) according to 'PcdH2OBoardId'.
The output package is a pure package data without "end block".
If corresponding package not found in source, system will use default package patch it.
@param[in] FirstImageBlockHeader A pointer to source image package from package list buffer.
@param[out] PackageData Output an address of a new buffer of parsed package data
if whole progress runs successfully.
Output a NULL if process failed.
This buffer should be freed by caller when image package
installation finished.
@param[out] PackageDataLength Output a length of new buffer.
@retval EFI_SUCCESS EFI_SUCCESS.
@retval EFI_INVALID_PARAMETER FirstImageBlockHeader is NULL or PackageData is NULL or
PackageDataLength is NULL.
@retval EFI_UNSUPPORTED Input source is not a multi image package
(The first block should be a H2O_HII_IIBT_BOARDS_BLOCK).
Binary format error or violation occured during the parsing.
