DrmFbImporter can outlive DrmDevice which will cause issues when
resources are released. Addressing this would require a restructure
on how ResourceManager stores DrmDevices and DrmFbImporter to make
sure they depend on each other. For now, just acquire the DRM fd from
the DrmDevice to make sure it is not closed.

It's a pain to use logcat filters for drm_hwcomposer since each file has a different tag necessitating one to specify each tag for the logcat filter or use a regex.
Use one tag for all of drm_hwcomposer to simplify this.

We use too much dup() system calls for present fence propagating.
Also when propagating acquire fence we use additional logic for
skipping such propagation for the validate/test cycle.
Both issues can be solved by introducing SharedFd, which will track
reference count of fd object.
After that the UniqueFd is used very rarely and can be simplified by
wrapping it into std::unique_ptr without caring too much of adding
an extra malloc/free operation.

Address new clang-tidy findings, in most cases 'misc-const-correctness'
check was addressed by adding 'const' modifier, or in some cases changed
to 'auto' (where it's better for formatting).

1. Move drm/DrmConnector.h to Normal clang-tidy checks list by fixing
clang-tidy findings.
2. Remove DrmDevice self-reference.
3. Replace shared_ptr reference to DrmDevice in DrmFbImporter with a
pointer, making ResourceManager only owner of DrmDevice and its
chilren.

Android-9 has -Wsign-compare enabled by default and it causes build issues.
Enable -Wsign-compare option in CI, so we won't introduce such issues anymore.

Video (YUV) frames can have several planes in the same buffer,
in this case all the planes will be represented by the same
gem_handle, which must be closed only once.
Fixes logcat noise during video playback.

DRM framebuffer objects must be kept registered in DRM/KMS
while used for scanning-out (After atomic commit applied
for processing by display controller and until next atomic
commit is applied for processing).
Existing logic for tracking current state is overcomplicated and
needs to be redesigned. Also further developing of drm_hwc will
require migration to asynchronous atomic commit, so additional
asynchronous FB cleanup logic must be created.
Buffer caching logic will also benefit from this.
With the RAII all further changes will be less painful and more robust.
By this commit I also renamed DrmGenericImporter to DrmFbImporter:
'Fb' word is present in most of existing composers (android and linux)
so it will be easier to compare different implementations.
