deps: updates wazero to v1.7.0

evacchi commented 8 months ago

This will update wazero to v1.7.0. The v1.7.0. release marks a milestone in the wazero project, replacing our old compiler architecture with a new optimizing compiler backend.. It also introduces experimental support to the thread spec.

We will officially announce the final v1.7.0 release in just a few days, during Wasm I/O, after which we will undraft this PR and update it to the latest tag.

~Let me know if you'd rather merge this PR before the official release. This draft PR is intended to let your CI checks run and verify everything is in order before our final release.~

What type of PR is this?

/kind feature

Does this PR introduce a user-facing change?

NONE

What are the benchmark results of this change?

the optimizing compiler brings >40% run-time improvement at the cost of slightly slower compile-time; that is a one-time cost you only pay at boot time, and we can setup a persistent file cache if that's an issue
