Reworked version of #15537
Difference with original PR:
- sort $names array to ensure its order does not affect caching, added test for it
- minor tweaks for cache key format
- used `foreach` instead of `array_map`
P.S. I'm not proficient with tests so not sure if tests are correct.

The way we can add functions to an ExpressionLanguage instance is by using inheritance. #10512 tries to make the expression language in the routing flexible but using inheritance won't work when several bundles want to add functions.
So, this PR takes another approach to solve the problem globally.
Todo:
* [x] add some more tests
* [ ] add some docs
