media: Remove IsPotentiallySupportedKeySystem()

This function is no longer needed. It was used to filter out key systems
that were not known to Chromium and thus were not likely to be
implemented in an interoperable way. However, this has not been useful
in the past and is creating an exception to have key system specific
code in media/.

This change removes this function to make it easier to support other key
systems.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

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.
