node_modules linker refactor

[Silic0nS0ldier]

This PR adds a new node_modules linker script and;

• Adds Rules JS and Rules TS.
• Adds dependencies via pnpm.
• Indirectly adds Rules NodeJS v5.

The linker script itself is a refactor which constraints node_modules symlink creation to under [name].runfiles/, and performs the symlink creation in a fault tolerant manner (as multiple processes may be trying to create it at the same time).

This also includes part of a workaround for environments such as EngFlow which reset [name].runfiles/ when using remote persistent workers, where the information needed to create symlinks is exposed to user code (where it can be run in each worker loop iteration).

TODO

• Move distributed part of linker script so consumers don't attempt to process internal/linker/BUILD.bazel which loads dev dependencies.
• Rework PR description. Include explanation for why Rules JS dependency brought in.

Builtin build_bazel_rules_typescript depends on io_bazel_rules_go.
New dependency rules_ts depends on a different version of io_bazel_rules_go.

This approach isn't going to work. Closing this PR, will create a fresh one reusing the existing build logic.

For future reference, build logic in this PR came from 2b408d9.
