L. E. Segovia 410e77be6c cmake: Add Find Module to support Android and iOS consumers
This commit adds a Find Module implementing the necessary logic to link
against GStreamer, while implementing some extra bits to enhance the
compatibility.

The first addition is the `mobile` target, which implements the
monolithic `gstreamer_android` library, and which here gains
compatibility with Apple's operating systems.

The second addition is the handling of the basic GStreamer libraries as
`--whole-archive` when statically linked, which was ported from the
ndk-build project in Cerbero. This is not easy to do, as CMake suffers
from several issues that impede its proper usage of pkg-config:

- It cannot differentiate between system/compiler specific libraries
  e.g. `-lm`, `-ldl`, but especially `-framework Cocoa`.
- It does not support `--whole-archive` natively until 3.27
- It attempts to reorder flags blindly by separating them with spaces,
  thus requiring the use of `-Wl,` wrapping or (in the case of Apple
  frameworks) manual framework lookup

The third addition is the port of the Fontconfig and ca-certificates
bundling logic.
