Subject: [PATCH 15 0/7] Add VirtualPipelineHandler

Hi all,

This series adds virtual pipeline handler, which doesn't depend on any
hardware, like camera sensor or ISP. Currently the configuration
supports test patterns and images.

It passed the gitlab pipeline:
https://gitlab.freedesktop.org/chenghaoyang/libcamera/-/pipelines/1283778

I've also checked that it works on qcam.

Updates in v15:
- Fixed single/multi-stream test with releasing `created_` when
  destructed.
- Added FaceDetectMode support: Off.

Updates in v14:
- Refactored ImageFrames to keep a list of filepaths directly.

Updates in v13:
- Returned an errno in `FrameGenerete::generateFrame()`

Updates in v12:
- Added ImageFrameGenerator first, then add Parser.
- Removed ScaleMode argument, as only Fill is supported now.
- Fixed bug of Stream's configuration usage in configure().

Updates in v11:
- Allowed a single value in the config file's frame_rates field.

Updates in v10:
Apply fixes according to Jacopo's and Barnabás' comments.
- Split test_pattern and path fields in the yaml format.
- Let FrameGenerators control frameCount_.
- Fixed match() returning values.

Updates in v9: Allocate contiguous memory for planes in the same
FrameBuffer.

BR,
Harvey
