MdePkg,UefiCpuPkg: fix wrong DS bit and add helper to check it
In FEAT_LPA2, the location of the DS bit in TCR_EL2
depending on the value of HCR_EL2.E2H:
1. When HCR_EL2.E2H = 0, the DS bit is located at bit 32 in TCR_EL2.
2. When HCR_EL2.E2H = 1 (EL0&2), the DS bit is located at
bit 59 in TCR_EL2, which matches its position in TCR_EL1.
However, the current implementation checks only bit 59 to determine
whether LPA2 is enabled, even when HCR_EL2.E2H is not set.
To address this issue, this change adds the necessary definitions
and a helper function to correctly check whether LPA2 is enabled.
