SecurityPkg/RngDxe: Documentation/include/parameter cleanup
This patch:
-Update RngGetBytes() documentation to align the function
definition and declaration.
-Improve input parameter checking. Even though 'This'
it is not used, the parameter should always point to the
current EFI_RNG_PROTOCOL.
-Removes TimerLib inclusion as unused.
