OvmfPkg/AcpiPlatformDxe: split S3/S4 package into bytes

Browse Source 
This should be more compatible with AML parsers in practice
since older versions of ACPICA's OS support would not accept
the previous OVMF format (despite being spec compliant).
(For example, on OpenBSD 5.2 it caused a kernel crash)

ACPICA has fixed this issue in:
