[ET-VK][custom_ops] Standardize binary filenames to test_*.cpp

Five custom_ops test binaries did not follow the test_*.cpp naming convention used by the other 16. Rename them via sl mv (history-preserving) in both xplat and fbcode mirrors:

- add.cpp -> test_add.cpp
- choose_qparams_per_row.cpp -> test_choose_qparams_per_row.cpp
- q4gsw_linear.cpp -> test_q4gsw_linear.cpp
- q8csw_conv2d.cpp -> test_q8csw_conv2d.cpp
- q8csw_linear.cpp -> test_q8csw_linear.cpp

Also add a Buck target for test_q8ta_unary -- the source file existed but no target was defined, leaving the binary unbuildable in fbsource (xplat/executorch/backends/vulkan/test/custom_ops:test_q8ta_unary now resolves).

Updates to references:

- targets.bzl (xplat + fbcode mirrors) -- five define_custom_op_test_binary() call sites renamed; one new entry for test_q8ta_unary.
- CMakeLists.txt (xplat + fbcode mirrors) -- five add_operator_prototype() call sites renamed. test_q8ta_unary is not added to CMake here since it was not in the prior CMake list (existing latent gap; orthogonal to this rename).
- tools/skycastle/.../executorch_vulkan_eureka_unit_tests.sky -- four CI target paths updated. Display labels are also updated to match the binary name (test_q8csw_linear, etc.), consistent with the convention used by adjacent test_q8ta_* entries.
- tools/skycastle/.../executorch_vulkan_gpu_host_unit_tests.sky -- three CI target paths + labels updated (this file does not run q8csw_conv2d).
- fbcode/executorch/oss/.github/workflows/pull.yml + xplat mirror -- five OSS CI references updated, including the build_and_run.sh argument that runs the renamed test_add binary.
