BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1593
For every SMI occurrence, save and restore CR2 register only when SMM
on-demand paging support is enabled in 64 bit operation mode.
This is not a bug but to have better improvement of code.

based on review feedback.
Patch6 - Removed Global Cr2 instead used function parameter.
Patch7 - Removed checking Cr2 with 0 as per feedback.
Patch8 and 9 - Aligned with EDK2 Coding style.
