Add <uri-relative-filter-group> to intent filters.

Introduce new <uri-relative-filter-group> tag to define a new matching
rule where all matchers in the group must match. Each rule group will be
evaluated in the order they are defined in the manifest. These rules
will only be evaluated if no matches found in mDataPaths.

Each URI relative filter group can define matchers for URI fragments and
queries in addtion to paths.
