Make PlatformInitPreMem independent to IntelSiliconPkg and IntelFsp2W…

…rapperPkg (#293)

## Description

This driver is shared across different Silicon vendors. So it should not
use any Intel specific packages.

In order to achieve this, added a new lib `FspSupportLib` to isolate
silicon related PCDs

- [ ] Impacts functionality?
- [ ] Impacts security?
- [ ] Breaking change?
- [ ] Includes tests?
- [ ] Includes documentation?

## How This Was Tested

CI build passed.

## Integration Instructions

No additional change is required for the consuming platforms.
