Skip the closedcaption element tests if the
closedcaption option is disabled at compile
time (i.e. -Dclosedcaption=disabled).
v2: rename pangocairo_dep to avoid conflict
with later definition in ext/ttml/meson.build
as suggested by @tpm.

Makes sure their path gets added to the uninstalled environment
and makes sure they get included in the docs.

This element acts as a counterpart of line21encoder.
Also adds a simple test validating each element using the
other.

This is the inverse of ccextractor: it takes a video and closed caption
stream and places the closed caption metas on the video output buffers.

The only plugins remaining are those that haven't been ported to Meson
yet, and msdk. Also, the tests are still automagic.

This new element allows decoding and overlaying CEA-708 Closed Caption
streams over video.
* Supports CDP and cc_data closedcaption/x-cea-708 streams
* Uses pango to render CC stream
* Support GstVideoOverlayComposition meta if downstream supports is
Tested on various test files.
Remains to be fixed/improved:
* Switch to GstByteReader (for code safety)
* Switch to GString (instead of manual pango string construction)
* Move pango/rendering code outside of main 708 decoder file (so
that actual CC parser/decoder can be (re)used in other scenarios).
Initial patches and improvements by:
* CableLabs RUIH-RI Team <ruihri@cablelabs.com>
* Steve Maynard <steve@secondstryke.com>
* cjun.wang" <cjun.wang@samsung.com>
