Some xtasks a developer will want to run regularly (like bundling up artifacts for wasm or embedded as part of their debug cycle). Some developers might rarely run, like some code-gen.

Similar for a CI. Multiple independent jobs will need to build the xtasks. Most jobs will just need the ones related to CI. Only one job will need to validate code-gen. Only a couple of jobs, conditioned on version tags, will need to call xtask dist.

By putting all of these into a single binary, we're losing out on performance by requiring it to build dependencies or run build scripts for xtasks that won't be run
