gstreamer1.0-plugins-bad: Transition to meson based builds

This update follows [427eb30f9b59972b38ae3f25094470bb7034547d]
in upstream, which trasnitions the gstreamer1.0 plugins build
from autotools to meson build.

Additional patches included in meta-freescale are:
- Backport of 2 patches to allow using OpenCV version 4.1.0
- Adaptions required in NXP fork to use meson
- One patch which solves the data dir search on OpenCV.

+Subject: [PATCH 1/2] meson: build gir even when cross-compiling if
+ introspection was enabled explicitly
+
+This can be made to work in certain circumstances when
+cross-compiling, so default to not building g-i stuff
+when cross-compiling, but allow it if introspection was
+enabled explicitly via -Dintrospection=enabled.
+
+See gstreamer/gstreamer#454 and gstreamer/gstreamer#381.
