OvmfPkg/MemEncryptSevLib: clean up InternalMemEncryptSevSetMemoryEncrypted() decl 

The declaration and the definition(s) of the function should have
identical leading comments and/or identical parameter lists. Document the
"Cr3BaseAddress" parameter, and correct several parameter references.
Replace a "clear" reference to the C-bit with a "set" reference.
