Pull request overview

This PR updates the Buck build definition for extension/kernel_util/test as part of a broader migration/rename from TARGETS to BUCK.

Changes:

• Added build_file_migration.bzl macro imports to the build file.
• Replaced a direct define_common_targets() invocation with a fbcode_target(_kind = define_common_targets, ...) wrapper.

Comments suppressed due to low confidence (1)

extension/kernel_util/test/BUCK:10

• This BUCK file now only invokes define_common_targets via fbcode_target(...), which likely means the common test targets are no longer defined for the non-fbcode/xplat build context. This is also indicated by non_fbcode_target being loaded but never used. If this directory previously had both a BUCK and a TARGETS file that each called define_common_targets(), the merged BUCK should typically call non_fbcode_target(_kind = define_common_targets, ...) for the xplat half and fbcode_target(_kind = define_common_targets, ...) for the fbcode half (see the pattern used in extension/memory_allocator/test/BUCK).
