Fix starlark lint errors in kotlin_library BUCK file

Summary:
D93521644 introduced conditional target definitions using variables (`_uses_ksp_and_ap`, `_ksp_generates`, `_uses_ksp_and_kapt`) that are assigned but never used. The diff used `# buildifier: disable=unused-variable` comments to suppress buildifier warnings, but this doesn't work for Buck2's starlark linter which uses a different suppression format.

The starlark linter has an `unused-assign` lint rule that flags these unused variable assignments. The correct suppression format is `# starlark-lint-disable unused-assign`.

This fix adds `# starlark-lint-disable unused-assign` comments alongside the existing `# buildifier: disable=unused-variable` comments for the three affected variables:
- `_uses_ksp_and_ap`
- `_ksp_generates`
- `_uses_ksp_and_kapt`

Both comments are needed:
- `# buildifier: disable=unused-variable` - suppresses buildifier warnings
- `# starlark-lint-disable unused-assign` - suppresses Buck2 starlark linter warnings

This resolves the `test_lint_buck2` test failure which runs `buck starlark lint buck2` and checks for lint errors in all Starlark files under the buck2 directory.
