Add IsEmpty and SizeIs matchers for ranges/containers
`SizeIs` can accept both `size_t` and a matcher. In the first case, it checks whether the size of the range is equal to specified size. In the second case, it checks whether the provided matcher accepts the size of the range.

* This does not change `TEST_CASE` and friends in any way
|
||||
* `IStreamingReporter::IsMulti` member function was removed
|
||||
* This is _very_ unlikely to actually affect anyone, as it was default-implemented in the interface, and only used internally
|
||||
* Various classes not designed for user-extension have been made final
|
||||
* `ListeningReporter` is now `final`
|
||||
* Concrete Matchers (e.g. `UnorderedEquals` vector matcher) are now `final`
|
||||
* `ListeningReporter` is now final
|
||||
|
||||
|
||||
|
||||
### Improvements
|
||||
* Matchers have been extended with the ability to use different signatures of `match` (#1307, #1553, #1554, #1843)
|
||||
* This includes having templated `match` member function
