remove error type variants suffixed with Bytes

We reserved these extra error types with the goal of possibly returning
the source `Bytes` in the error type, but no one has since need this.
Since the dependency on `bytes` is being made private, it made sense to
remove these otherwise unused error types.

Removes:

- `InvalidUriBytes`
- `InvalidHeaderNameBytes`
- `InvalidHeaderValueBytes`
