UefiPayloadPkg: Remove asm code and sharing libraries

Remove asm code used for payload entry.
Use patchable PCD instead a fixed PCD PcdPayloadStackTop to avoid
potential conflict.

Based on the removal, use same HobLib regardless UNIVERSAL_PAYLOAD.
Use same PlatformHookLib regardless UNIVERSAL_PAYLOAD. The original
PlatformHookLib was removed and UniversalPayloadPlatformHookLib was
rename to new PlatformHookLib.
