build: don't use Nx cache

[samestep]

Description

This PR removes the monorepo build artifact caching added by #1081 and #1142, also removing the need for #1175. In practice, my observation has been that most of our tasks are either very fast (e.g. esbuild) or already cache automatically (e.g. Cargo), and that for the ones that aren't super fast (e.g. Vite build in components or editor), Nx usually doesn't cache those anyway because their dependencies changed. Furthermore, it requires a lot of configuration to correctly identify cache hits; so far we've only been specifying the outputs of each task and not the inputs, so Nx usually reruns tasks unnecessarily because it sees changes in the output artifacts of downstream tasks and conservatively assumes that those might affect things. On the flipside, I've also often found myself running rm -r node_modules/.cache/ just to be sure that Nx isn't caching things incorrectly. Specifically, some of our scripts (e.g. wasm-bindgen) don't delete the contents of their output directory before writing to it, so if they aren't writing as many files as they were before, Nx will still pick those up and put them in the cache even though they aren't outputs of the current task run. In theory we could deal with this by manually deleting these output directories before writing to them, but even that doesn't really seem feasible: for instance, if we were to always delete target/ before running Cargo, that would get rid of its own caching abilities, which wouldn't be worth it.
