meson: Only build pipeline handlers needed in the host architecture

Browse source 
By default all pipeline handlers are built, regardless on whether these
are needed in the host architecture or not. It makes more sense to build
only the pipeline handlers that will be used for the given architecture.

Let's do that by default now, but still allow to build the other
pipeline handlers if needed, by using the `pipelines` meson option. For
example, on a x86-64 platform:

  $ meson build
  ...
    Configuration
    Enabled pipelines        : ipu3
                               uvcvideo
    Enabled IPA modules      : ipu3
  ...

  $ meson build -Dpipelines="ipu3,raspberrypi,rkisp1" -Dtest=true
  ...
    Configuration
    Enabled pipelines        : ipu3
                               raspberrypi
                               rkisp1
                               vimc
    Enabled IPA modules      : ipu3
                               raspberrypi
                               rkisp1
                               vimc
  ...
