Add following V4L2 QP parameters for H.264:
* V4L2_CID_MPEG_VIDEO_H264_I_FRAME_MIN_QP
* V4L2_CID_MPEG_VIDEO_H264_I_FRAME_MAX_QP
* V4L2_CID_MPEG_VIDEO_H264_P_FRAME_MIN_QP
* V4L2_CID_MPEG_VIDEO_H264_P_FRAME_MAX_QP
These controls will limit QP range for intra and inter frame,
provide more manual control to improve video encode quality.

Avoid cell overlapping by changing some sizes, and changing the
font sizes when needed.

The extended-controls.rst file had become too big. Split it up: each
control class reference gets its own rst file, and this file just
describes the Extended Control API.
Each control class reference is also moved up one level into the
table of contents to make it easier to find e.g. the codec control
reference.
Finally I rearranged the order so that all camera-related control
classes are grouped together, ditto for codec/jpeg and fm-rx/tx.
The ext-ctrls-codec.rst is still pretty big and it is a candidate
to split up further in the future, possibly per codec.
