Ci performance improvements

[vigoo]

• Enable wasmtime fs cache in compilation cache service (was already in executor) so it affects integration tests too
• Removes the component name = wit package name validation that made sense when people were manually creating WIT packages but not anymore; this means we don't have to patch test components, so the wasmtime compilation cache can work always
• Using the quick profile for TS (and scala) on CI, that skips the wizer step
• cargo-binstall for wasm-rquickjs
• split some more IT tests for more parallelism

Results:

• wall clock 44m -> ~31m
• total compute down by ~1h

Build phase: -1m
Test component build phase: -5m
Test phase: -7m
