Pull request overview

Migrates ExecuTorch devtools Buck build definitions by consolidating legacy TARGETS content into BUCK files and wrapping targets using the build-file migration macros, aligning these directories with the BUCK-based build file naming/layout.

Changes:

• Removed devtools/bundled_program/TARGETS and merged its rules into devtools/bundled_program/BUCK.
• Updated several devtools/**/BUCK files to wrap rule definitions with fbcode_target (and, where applicable, non_fbcode_target) via build_file_migration.bzl.
• Preserved existing target structure (names/deps/visibility) while shifting to the new wrapper-based declaration style.
