payloads/edk2: Disable the CPU Timer Lib unless supported
For recent X86 CPUs, the 0x15 CPUID instruction will return Time Stamp
Counter Frequence. For CPUs that do not support this instruction, EDK2
must include a different library which is the reason why this must be
configured at build time.
If this is enabled, and the CPU doesn't support 0x15, it will fail to
boot. If is not enabled, and the CPU does support 0x15, it will still
boot but without support for the leaf. Consequently, disabled it by
default.
