FmpDevicePkg/FmpDxe: Improve handling of XDR certs
The current implementation for XDR certificate handling assumes the
PublicKeyDataXdr buffer is 4-byte aligned. This is not always the case.
For example, if PublicKeyDataXdr=0x02, and the length is 0x05, the
correct offset should be 0x2 + align_up(0x5, 4) -> 0x2 + 0x8 = 0xA. The
current logic produces align_up(0x2 + 0x5, 4) -> align_up(0x7, 4) = 0x8.
