PeilessStartupLib is running in SEC phase. In this phase global variable
is not allowed to be modified. This patch moves mPageTablePool to stack
and pass it as input parameter between functions.

PeilessStarupLib provides a function (PeilessStartup) which brings
up both Legacy and Tdx guest from SEC phase to DXE phase. PEI phase
is skipped so that the attack surfaces are reduced as much as possible.
PeilessStartup() does below tasks:
1. Contruct the FW hoblist.
Since PEI is skipped, we must find a memory region which is the
largest one below 4GB. Then this memory region will be used as the
firmware hoblist.
2. Initialize the platform.
3. Build various Hobs, such as SecFv Hob, DxeFv Hob, Stack Hob, etc.
4. At last DXE Core is located / loaded and transfer control to it.
