This commit extends the Matchers feature with the ability to have type-independent (e.g. templated) matchers. This is done by adding a new base type that Matchers can extend, `MatcherGenericBase`, and overloads of operators `!`, `&&` and `||` that handle matchers extending `MatcherGenericBase` in a special manner. These new matchers can also take their arguments as values and non-const references. Closes #1307 Closes #1553 Closes #1554 Co-authored-by: Martin Hořeňovský <martin.horenovsky@gmail.com>
