Subject: [edk2-BuildSpecification PATCH] Use macros in !include file paths

https://bugzilla.tianocore.org/show_bug.cgi?id=472

The EBNF already allows !include statements to use
$(MACRO) values in the file path.  This change updates the description and examples for !include statements to allow the use of macros and specific environment variables in !include file paths.
