Describe the use-case for this feature

As it is now it is not possible to do the sbt equivalent of fullLinkJS/fastLinkJS in sbt when integrating with BSP + bloop. Bloop has support for this through the link command.

This might also be relevant in the future in regards to Kotlin and KMP (although I know nothing about that besides it also compiles to JS/wasm/LLVM.

What do you propose

An interface similar to BuildTargetTest/Run for linker tasks.

I've checked to make sure there isn't already a way to support this in the current protocol
