This commit adds support of out-of-tree plugins autoloading using python package entry point specification: * https://packaging.python.org/en/latest/specifications/entry-points/#entry-points * https://packaging.python.org/en/latest/guides/creating-and-discovering-plugins/#using-package-metadata Out-of-tree plugins must register entry points as `torchcodec.backends`: ``` [project.entry-points.'torchcodec.backends'] device_backend = 'torchcodec_plugin:load_plugin' ``` Torchcodec will automatically load plugins if discovered. Loading can be explicitly suppressed with `TORCHCODEC_DEVICE_BACKEND_AUTOLOAD=1` environment variable. The same approach is being used to load PyTorch device backends.
