Add panicking helpers for getting components from Query (#9659)

# Objective

- Currently we don't have panicking alternative for getting components
from `Query` like for resources. Partially addresses #9443.

## Solution

- Add these functions.

---

## Changelog

### Added

- `Query::component` and `Query::component_mut` to get specific
component from query and panic on error.
