Implement predicate-based decoder selection
This CL revamps the way a VideoDecoder or AudioDecoder is selected to
decode a given VideoDecoderConfig or AudioDecoderConfig, respectively.
The goal is to first filter and rank available decoders based on their
high-level attributes ("IsPlatformDecoder", "SupportsDecryption"),
rather than attempting to initialize them in the order they're
submitted. The result is that an initial decoder is selected more
efficiently, and the decoding system can gracefully transition between
platform and non-platform decoders if the config changes mid-stream.

Documentation in the source is rooted in docs/README.md.
Learn how to Get Around the Chromium Source Code Directory Structure .
For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
