meson: Rework automatic pipeline selection

Browse source 
The supported pipelines are listed in three places: the
meson_options.txt file, the defined array when a user selects
-Dpipelines="all", and arrays defined when the default
-Dpipelines="auto" is selected.

This can be hard to maintain and error prone.

Rework the definition of pipeline selection to a single table which
specifies the architecture(s) that the pipeline handler supports and
iterate it to handle the special cases for 'all', 'auto' and 'test'.

The current behaviour such that 'all' takes precedence over 'auto' is
maintained, and 'test' is now extended such that additional test
pipeline handlers can easily be introduced.

The existing implementation defines the i.MX8-ISI and RKISP1 pipeline
handlers as only supported by 'aarch64'. This conversion changes the
behaviour such that those pipeline handlers are now supported on both
'arm' and 'aarch64' as each of those platforms could support a 32-bit
ARM build.
