Inject regexp language into wildcard_constraints section params values

[iromeo]

Inject regexp language into wildcard_constraints section params values. Consider using PythonRegexpLanguage instead of default RegexpLanguage. Support both top-level and rule section declaration types.

Could be useful: SmkSLRegExpElementType or likely SmkSLInjector but inject PythonRegexpLanguage

Wildcards are parsing by

def regex(filepattern):
    f = []
    last = 0
    wildcards = set()
    for match in _wildcard_regex.finditer(filepattern):
        f.append(re.escape(filepattern[last : match.start()]))
        wildcard = match.group("name")
        if wildcard in wildcards:
            if match.group("constraint"):
                raise ValueError(
                    "Constraint regex must be defined only in the first "
                    "occurence of the wildcard in a string."
                )
            f.append("(?P={})".format(wildcard))
        else:
            wildcards.add(wildcard)
            f.append(
                "(?P<{}>{})".format(
                    wildcard,
                    match.group("constraint") if match.group("constraint") else ".+",
                )
            )
        last = match.end()
    f.append(re.escape(filepattern[last:]))
    f.append("$")  # ensure that the match spans the whole file
    return "".join(f)

inside

    def regex(self):
        if self._regex is None:
            # compile a regular expression
            self._regex = re.compile(regex(self.file))
        return self._regex
