Labels: Add DropMetricName function, used in PromQL (#13446) 
This function is called very frequently when executing PromQL functions,
and we can do it much more efficiently inside Labels.

In the common case that `__name__` comes first in the labels, we simply
re-point to start at the next label, which is nearly free.

`DropMetricName` is now so cheap I removed the cache - benchmarks show
everything still goes faster.
