Improved readability of matcher-related deprecations

* Include stack traces. This makes it easier to find the matcher that
needs to be updated, particularly when it comes from a library rather
than the user's own code.

* Show each deprecation only once unless `config.verboseDeprecations`
is set. Since matchers are often added in a global `beforeEach`, logging
deprecations every time can be overwhelming.
