Add Route#handleErrorRequestZIO

[mschuwalow]

Is your feature request related to a problem? Please describe.
Not related to an usecase, but I noticed that handleErrorRequest is the only error handling function that does not have a ZIO counterpart. I propose adding it for symmetry and ocd purposes.

Describe the solution you'd like
Add a Route#handleErrorRequestZIO that is similiar to Route#handleErrorRequest, but allow passing a function producing a zio effect.
