Subject: [PATCH] optimize all dependencies for tests (#9980)

The runtime of the whole test suite gets down, on my test VM, from 224
seconds to 138 seconds, ie. 40% faster. Single-threaded runs show a 30%
speedup over the whole test suite.

Integration tests show a 35% multi-threaded speedup, and 30%
single-threaded speedup.

As for the bigger simple crates:
- near-vm-runner shows a decrease from 62s to 30s, ie. 50% speedup.
Single-threaded tests show a 65% speedup.
- near-chain only shows a 10% speedup
- near-store shows a 25% speedup, or 35% single-threaded
- estimator-warehouse does not change, as it already rebuilds internally
with optimizations

As for the time to build, building the whole test suite, including
dependencies, is 20% slower, with 18 minutes to build as opposed to 15
minutes before, so a decrease in performance of 3 minutes.

However, we only rarely build dependencies, especially considering we
(should) carefully review each added or upgraded dependency. As a
consequence, I think that this 3-minutes-every-week-or-so is worth the
compile-and-test cycle speed improvements. Especially considering that
15 minutes is already enough for it to be a background job, whereas eg.
near-vm-runner tests taking 30s instead of 68s can lead to one fewer
context switch.

CI times should not change, as they already build with the quick-release
profile.

The gains with `opt-level = 3` are basically the same as the ones from
this PR.

Replaces #9673.
