[yocto-docs PATCH v3 0/2] Document how to provide configuration from layer.conf

[Antonin Godard <antonin.godard@bootlin.com>]

This series documents how to provide configurations from layer.conf, be
it unconditionally or conditionally. I wanted to reference a file in
bitbake, so I added the :bitbake_git: new term for that.

This is a attempt at closing

Changes in v3:
- Replace attention block by warning block.
- Create an anchor for the conditional confs section, I was getting a
  sphinx error.
- Rephrase the PREFERRED_PROVIDER sentence.
- More precision on PREFERRED_PROVIDER assignments, with other conf
  files..
- Link to v2: https://lore.kernel.org/r/20241112-layer-confs-v2-0-22a09f1a0a8e@bootlin.com

Changes in v2:
- Create an `.. attention::` block to tell users _not_ to set
  unconditional confs from layer.conf.
- Fix typos reported by Quentin (thanks!)
- Add "Reviewed-by: Quentin Schulz <quentin.schulz@cherry.de>" on first
  commit (thanks!).
- Simplify "your layer is part of BBLAYERS" 🡒 "your layer is part of the
  build".
- Fix code blocks spacing (three spaces).
- Link to v1: https://lore.kernel.org/r/20241030-layer-confs-v1-0-0f7dcf460e27@bootlin.com
