libcamera: Rationalize IPA and handlers names

The names used by the IPA interface and the names used for buffer
completions handlers in libcamera clash in the use of the term "buffer".

For example video device buffer completion handler is called
"bufferReady" and the IPA event to ask the IPA to compute parameters are
called "fillParamsBuffers". This makes it hard to recognize which
function handles video device completion signals and which ones handle
the IPA interface events.

Rationalize the naming scheme in the IPA interface function and events
and the signal handlers in the pipelines,  according to the
following table. Remove the name "buffer" from the IPA interface events
and events handler and reserve it for the buffer completion handlers.
Rename the IPA interface events and function to use the 'params' and
'stats' names as well.

IPA Interface:

- fillParamsBuffer -> computeParams   [FUNCTION]
- processStatsBuffer -> processStats  [FUNCTION]
- paramFilled -> paramsComputed       [EVENT]

Pipeline handler:

- bufferReady -> videoBufferReady     [BUFFER HANDLER]
- paramReady -> paramBufferReady      [BUFFER HANDLER]
- statReady -> statBufferReady        [BUFFER HANDLER]
- paramFilled -> paramsComputed       [IPA EVENT HANDLER]

Cosmetic change only, no functional changes intended.
