`ParameterFormatter` rewrite with corrected escape handling

I have created #1639 <https://github.com/apache/logging-log4j2/pull/1639>
fixing #1626. There I rewrote `ParameterFormatter`, which is a crucial
performance-sensitive core component. *I will appreciate some review
from others.*

In a nutshell, given certain input, the earlier version was either throwing
`ArrayIndexOutOfBoundsException` or formatting escaped escapes incorrectly.

In the meantime, I will adapt the performance tests and make sure that
there are no regressions.
