script: Move webaudio DOM interfaces to script/dom/audio/ (#38894)
Moves interfaces defined by the webaudio spec (27 files) to the new `script/dom/audio/` module from the `script/dom/` module. Testing: Just a refactor shouldn't need any testing Fixes: N/A Signed-off-by: Ashwin Naren <arihant2math@gmail.com>
