BRP strict field in query (#16725)

# Objective

- Allow skiping components that don't have ComponentId yet instead of
failing `bevy/query` request.

## Solution

- Describe the solution used to achieve the objective above.

## Testing

My naive approach boils down to:
- bevy/list to get list of all components.
- bevy/query with empty components and has fields and a option that
contains result of the bevy/list.

Before that change I end up with bunch of `Component xxx isn't used in
the world` because some of the components wasn't spawned at any moment
yet in the game. Now it should work.

## Migration Guide

- `BrpQueryParams` now has `strict` boolean field. It serfs as a flag to
fail when encountering an invalid component rather than skipping it.
Defaults to false.
