Pull request overview

Renames/migrates Buck build definitions by moving targets from TARGETS to BUCK and wrapping target declarations with migration macros to support fbcode vs non-fbcode environments.

Changes:

• Convert extension/audio/BUCK targets to use fbcode_target wrappers.
• Remove extension/aten_util/test/TARGETS and merge its intent into extension/aten_util/test/BUCK.
• Introduce fbcode_target/non_fbcode_target wrappers in extension/aten_util/test/BUCK to conditionally define common targets.

File	Description
extension/audio/BUCK	Wrap existing python targets using migration macros for fbcode/non-fbcode handling.
extension/aten_util/test/TARGETS	Remove legacy TARGETS entrypoint now that definitions are merged into BUCK.
extension/aten_util/test/BUCK	Add migration wrappers and merge prior TARGETS guidance/callsite into BUCK.

• non_fbcode_target is loaded here but never used in this file. Consider removing it from the load(...) (or wrapping targets that should exist in non-fbcode builds with non_fbcode_target) to avoid unused/ambiguous migration imports.
