Add NDK version 34

[tosti007]

The minimal android SDK version required by the Google Play store to be able to publish an app has been bumped to version 34. However the current release of xbuild does not support this, being maxed at 33.

As far as I can tell all that really needs to happen is for the sdk workflow to be re-run (possibly with minor updates, I'm not sure). It simply packages the sdk libs and puts them on the release assets page, and the ubuntu-latest runner image which is used (at least for the linux part of that workflow) contains SDK versions 33-35.

Then the hard-coded link in the xbuild source would have to be updated to pull the latest release assets for the SDK as before.

PS As a temporary workaround, I copied my standalone android sdk platform and ndk libs into ~/.cache/x/, in the same layout as what's already there, and changed the version to 34 in the xbuild src. That got things working for me, in case you need a hacky workaround until this gets fixed.

Alternatively, the cargo-mobile2 tool by the tauri peeps uses whatever android system you have installed, so you're fairly free to do as you please with that, though their android support is in the process of being updated.
