Milan Zamazal 79a75b9088 libcamera: software_isp: Make measurement configurable ...

Software ISP performs performance measurement on certain part of initial
frames.  Let's make this range configurable.

For this purpose, this patch introduces new configuration options
software_isp.measure.skip and software_isp.measure.number.  Setting the
latter one to 0 disables the measurement.

Instead of the last frame, the class member and its configuration
specify the number of frames to measure.  This is easier to use for
users and doesn't require to adjust two configuration parameters when
the number of the initially skipped frames is changed.

The patch also changes the names of the class members to make them more
accurate.

Completes software ISP TODO #7.
