payloads/edk2: Add Kconfig to use LAPIC timer
Core 2 platforms have issues with HPET. Enable support to use the LAPIC
driver so those machines actually boot and don't hang.
The LAPIC is actually closer to the CPU than the HPET (on the PCH),
which reduces access latency, leading to higher resolution of the timer.
Tested on a Lenovo X200 with a Core 2 Duo.
