Pull request overview

Renames/merges fbcode TARGETS build definitions into BUCK files for several ExecuTorch runtime/kernel directories, using fbcode_target/non_fbcode_target wrappers to keep fbcode vs xplat behavior separated within a single build file.

Changes:

• Convert kernels/prim_ops, kernels/portable/test, and kernels/portable/cpu/util/test from TARGETS to BUCK by merging definitions and adding fbcode_target/non_fbcode_target wrappers.
• Update runtime/BUCK to wrap the Python library target with fbcode_target.
• Remove the now-redundant TARGETS files in the affected directories.

runtime/BUCK:6

• non_fbcode_target is loaded here but never referenced in this BUCK file. If the target is intended to be fbcode-only, drop the unused symbol from the load(...) to avoid Buck/bucklint unused-load failures; otherwise wrap an appropriate target with non_fbcode_target as well.
