OvmfPkg: make PcdQ35TsegMbytes dynamic 

We can now make PcdQ35TsegMbytes dynamic, in preparation for the extended
TSEG size feature. At the moment we only move the declaration in
OvmfPkg.dec from [PcdsFixedAtBuild] to [PcdsDynamic, PcdsDynamicEx], and
provide the dynamic defaults (with the same value, 8) in the DSC files if
SMM_REQUIRE is TRUE.
