Change preferred license of EDK II to BSD+Patent

https://bugzilla.tianocore.org/show_bug.cgi?id=1656

Change the EDK II C Coding Standards Specification to state that
the preferred license of the EDK II is the BSD+Patent License and
that file headers should use SPDX license identifiers.

Remove the requirement that there are no blank lines between
the copyright statement and the SPDX identifier.  This rule is not
consistently followed.
