SecurityPkg: Fix incorrect return value when File is NULL
The DxeTpmMeasureBootHandler and DxeTpm2MeasureBootHandler handlers
are SECURITY2_FILE_AUTHENTICATION_HANDLER prototype. This prototype
can not return EFI_INVALID_PARAMETER.
The prototype documentation states it returns EFI_ACCESS_DENIED if:
"The file specified by File and FileBuffer did not authenticate,
and the platform policy dictates that the DXE Foundation may not
use File."
Correct the documentation, and add a early check, returning
EFI_ACCESS_DENIED when File is NULL.
Noticed while reviewing commit 6d57592740cdd0b6868baeef7929d6e6fef.
