pw_metric: add _STATIC variants

This adds PW_METRIC_STATIC and PW_METRIC_GROUP_STATIC, which do the same
as their non-_STATIC siblings, except that the object that they create
gets a `static` storage.

This can be useful, e.g. to have metrics inside of functions, when the
function itself is to be instrumented.

This CL also removes an extraneous stringification in the metric and
group names, which resulted in double double quotes.

Ah, and I also implemented PW_METRIC_GROUP with 3 parameters, which was
referenced in the documentation but not formally implemented.
