Improve compile/typecheck performance

[aloucks]

Objective

#18103 (or at least significantly improves the situation)

Solution

Removed default-features = false from the bevy_* [dev-dependencies].

Testing

cargo check and rust-analayzer are now significantly faster.

[aloucks]

It's probably worth investigating build-override opt-level too.

you should also remove the few default features of the crates that have some, and only enable them when needed

I don't understand why this would work; can you explain more?

It had initially helped cargo check times for me in Rust-Analyzer and I initially believed it was due to the resolver wanting multiple copies of the crates with different feature sets. I've had issue with R-A being quite slow for a while now. A fresh cargo clean would sometimes fix the problem initially, but it would always return. I haven't yet experienced the issue after the last clean and suspect the problem is likely an R-A issue and not the same issue that @h3r2tic was describing. I'm going to close this for now and will revisit later if I have more definitive evidence.
