[Cast Streaming] Split Cast streaming encoding out to a separate folder
This moves encoding for Cast Streaming into media/cast/encoding and separates it from the generic sender library. This will facilitate migration of the sender to libcast and future upstreaming of encoding to libcast. Bug: 1304256 Change-Id: Idc0dd6ecc157f052222054d04a0f71e862964c01 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3612383 Reviewed-by: Joe Downing <joedow@chromium.org> Reviewed-by: Ryan Keane <rwkeane@google.com> Commit-Queue: Mark Foltz <mfoltz@chromium.org> Cr-Commit-Position: refs/heads/main@{#997415}
