[RFC PATCH v1 00/12] apps: lc-compliance: Multi-stream tests

[Barnabás Pőcze]

This changeset adds multi-stream tests based on the last two commits of
https://patchwork.libcamera.org/project/libcamera/list/?series=4234

Similarly, only the last two commits here deal with multi-stream
tests directly. Most other changes are non-functional changes.

But notably, the libevent dependency of lc-compliance was removed
because it can be easily replace with C++ STL parts, and its use
was prone to race conditions.

One notable difference compared to the last patch of the aforementioned
series is that no new test is created, the current tests are kept
and are simply run with multiple streams.

    `Environment`
