…at wasm tests don't build dependencies

bump ui test crate

The recommended way to run tests locally is `./miri bless -- -- --quiet`, which will show

* progress bars
* the currently running tests (allowing you to see which ones are still running towards the end of the test suite)
* the output of the currently running tests (if they are slow). This means slow running tests can output lines to `stderr` and the last line will be shown after the test name and updated every few hundred milliseconds.

As a side effect this PR also fixes rust-lang#2998 and only builds dependencies if any tests actually need them (this means that with the next ui_test update we'll be able to merge all our test suites).

Also fixes rust-lang/miri#3052.

GC the Stacked Borrows allocation history

This handles the biggest contributor to rust-lang/miri#3080

The benchmark that this adds demonstrates the memory improvement here, but our benchmark setup doesn't record memory usage, and `hyperfine` doesn't support emitting memory usage stats. I ran this benchmark manually with `/usr/bin/time -v cargo +miri miri run` 🤷
