As the main branch is now bumped to 0.11, we would like to remove some deprecated functions.

The target is torchaudio.functional.angle.
The detailed context can be found #1337

Steps

1. Remove the implementation

2. Make sure the test passes.

Surprisingly, there seems to be no test for angle function, so it should be fine, but you can either run tests in local or make a PR and CI will kick off the tests.

Note

For setting up the development environment, please refer to CONTRIBUTING.md and torchaudio_unittest
