[PATCH 0/5] Add InfoFrame

[Harvey Yang]

Hi folks,

This series of patches adds MailBox, Pool and InfoFrame as helper
classes, which are useful to save duplicated code in the upcoming
mtkisp7 implementation. We also think that they're helpful for other
pipeline handlers.

It's based on the `Add VirtualPipelineHandler` series, as one
of the patch updates struct FrameBuffer.

We can also check if we should append DmaBufAllocator to support
strideAlign and scanAlign, so that InfoFramePool can save some
duplicated code.

It passed the gitlab pipeline:
https://gitlab.freedesktop.org/chenghaoyang/libcamera/-/pipelines/1286167

Please take a look. Thanks!

BR,
Harvey
