Subject: [PATCH 0/5] media: vimc: add RGB/YUV input entity and improve pipeline support

This series extends the vimc test driver with a new RGB/YUV input entity,
pipeline enhancements, and documentation updates.

Patch 1 adds an RGB/YUV input entity that can be used to simulate pipelines
starting after a real debayer stage.

Patch 2 adds V4L2_FIELD_ALTERNATE support to vimc-sensor, allowing it to
simulate interlaced sources.

Patch 3 extends the debayer to support multiple RGB output formats.

Patch 4 allows vimc-capture to accept custom bytesperline values so users can
exercise padded strides when testing the RGB/YUV path.

Patch 5 updates the vimc documentation with the RGB/YUV input entity and
revised media-ctl/v4l2-ctl examples.

Tested with:
  - vimc.0 on x86_64 using media-ctl and v4l2-ctl pipelines
