Debug messages that start as natural (English) language phrases (after the
debug prefix) should uniformly begin with lower-case or upper-case. In
SetMemoryEncDec() we have a mixture now. Stick with lower-case.
(Upper-case is better for full sentences that also end with punctuation.)

In SetMemoryEncDec(), we have four locations where we (a) log a message on
the DEBUG_WARN level that says "ERROR", (b) return the status code
RETURN_NO_MAPPING right after.
These messages clearly describe actual errors (bad PML4, PDPE, PDE, PTE).
Promote their debug levels to DEBUG_ERROR, and remove the word "ERROR"
from the messages.

In the SetMemoryEncDec() function, the way we currently report
PhysicalAddress is not uniform:
- mostly we say "for %lx",
- in one spot we say "at %lx" (even though the 2MB page being split does
not live *at* PhysicalAddress, instead it maps PhysicalAddress),
- in another spot we don't log PhysicalAddress at all (when splitting a
1GB page).
Unify this, using the format string "for Physical=0x%Lx".

None of the DEBUG macro invocations in SetMemoryEncDec() fit on a single
line. Break them to multiple lines, for (a) conforming to the coding style
spec, (b) easier modification in later patches.

Add Secure Encrypted Virtualization (SEV) helper library.
The library provides the routines to:
- set or clear memory encryption bit for a given memory region.
- query whether SEV is enabled.
