[Interest] Qt WebAssembly caching

Hello Qt WA devs,

I have noticed that Qt WA needs to load and recompile every time I start
the browse to the location of the application.

On the other hand, the WebAssembly Tanks demo seems to be cached and
doesn't need to reload https://webassembly.org/demo/Tanks/.

I've also found a blog post about caching WebAssembly from a PDF reader
toolkit (
https://pspdfkit.com/blog/2018/optimize-webassembly-startup-performance/#compiling-and-caching
).

I think it would be great if Qt WA also supports caching as the loading and
especially compile times are relatively high, especially on mobile devices.

Best regards,
Alex
