Add toolchain type for remaining actions

[kotlaja]

This is the first step for migrating to Automatic Exec Groups (check #19261).

I tried migrating with bazel build ... --incompatible_auto_exec_groups, fixed two actions added in this PR, and was stopped by the error:

ERROR: /usr/local/google/home/kotlaja/.cache/bazel/_bazel_kotlaja/3b1d6911411754876f642abf5e6636f0/external/rules_kotlin/kotlin/compiler/BUILD.bazel:22:22: in kt_js_import rule @@rules_kotlin//kotlin/compiler:kotlin-stdlib-js:

		ctx.actions.run(
Error in run: Couldn't identify if tools are from implicit dependencies or a toolchain. Please set the toolchain parameter. If you're not using a toolchain, set it to 'None'.

Still, I think this error will be fixed with upgrading to rules_kotlin 2.0.0.

Closing this PR since these changes will be managed internally and then exported to github.
