libcamera: Enable vimc pipeline handler when tests are enabled

The addition of the new IPA IPC mechanism compiles pipeline-specific
headers to define the interface between the pipeline and the IPA.

This was optimised in 08ce394465b5 ("meson: ipa, proxy: Only build
proxies for enabled pipelines") to only build for enabled pipelines,
however the tests directly use the VIMC pipeline handler, and require
it to be built.

Create a local variable to store the requested pipelines from the user
configuration and extend the enabled pipelines to ensure that VIMC is
always enabled if the tests are also enabled
