Add "filter_{exclude,include}" intrinsic functions to GN

Some templates in chromium abuses set_sources_assignment_filter to
filter elements out of a list. As set_sources_assignment_filter is
considered a mis-feature (and a consensus to remove it), there is
a need for an alternative way to filter lists of strings.

Add two intrinsics functions "function_exclude" & "filter_include"
that take a list of string and a list of pattern and return all
the elements from the first list that match respectively none or
at least one of the patterns.
