MdeModulePkg PeiCore: Remove the using of PcdPeiCoreMaxFvSupported

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1405

Background as below.

Problem:
As static configuration from the PCDs, the binary PeiCore (for example
in FSP binary with dispatch mode) could not predict how many FVs,
Files or PPIs for different platforms.

Burden:
Platform developers need configure the PCDs accordingly for different
platforms.

To solve the problem and remove the burden, we can update PeiCore to
remove the using of PcdPeiCoreMaxFvSupported, PcdPeiCoreMaxPeimPerFv
and PcdPeiCoreMaxPpiSupported by extending buffer dynamically for FV,
File and PPI management.

This patch removes the using of PcdPeiCoreMaxFvSupported in PeiCore.
