feat(wasm): Upgrade to uniffi 0.29.3 to support wasm targets

[zzorba]

Upgrade to what will soon be uniffi 0.29.3 (release is planned for next week). This mostly concerns an upgrade of the xtask orchestration system, but there were some small changes to the .udl spec that were needed as well.

This will likely produce issues with the complement-crypto package, which seems to still be using uniffi 0.25 to build.

• Public API changes documented in changelogs (optional)

Would be nice to have some docs. What does this config supplier do differently from the default upstream one?

[zzorba]

Which upstream class one are you seeing? I only see the trait and an 'Empty' supplier in the 2.9.x versions of Uniffi.

[jplatte]

I thought I had a seen a "default config supplier". There seem to be two upstream though: https://docs.rs/uniffi_bindgen/0.29.3/uniffi_bindgen/cargo_metadata/struct.CrateConfigSupplier.html is the other one.

What's the status of this PR?

[zzorba]

@Hywan this PR is still necessary, it upgrades us to the most recent uniffi (0.29.3) which contains support for Wasm targets. Without it the matrix-sdk-ffi crate will not compile.

It is unfortunately blocked on the complement-crypto library, which I believe is blocked on NordSecurity considering an upgrade I submitted NordSecurity/uniffi-bindgen-go#77.

I believe Matthew has asked someone to look into the complement-crypto issue, which I believe is currently monkey-patching to work with a very old version of uniffi.
