fix(device_info_plus)!: fixed webasm compliance

[arnaudruffin]

Description

This PR allows device_info_plus to be used in a web project compiled to webasm.

For that a type had to be changed (devicememory became a double?) and one converted from JStype to dart type.
I also took the liberty to update the example "index.html" file, as it was based on a deprecated template and not compatible with webasm compilation.

Most of this commit is a copy of what was done in #3161 by @GiacomoPignoni . Credits go to him.

Thanks @arnaudruffin this looks good to me now.

I marked the PR as breaking, because it changes a user facing class member type, even if it is just changing from int to double.

I would like to check a few things first. If all is good I will merge and release on Monday.

The web version on device_info_plus needs to be set to ^1.0.0, otherwise if Flutter resolves web 0.5 it won't compile.

I tried to push the commit, but GitHub rejected the push (did you enable allowing maintainers to push changes?)

Hi @arnaudruffin can you do the requested changes? otherwise I will have to close the PR and create a new one.

[miquelbeltran]

I managed to push the change to your main branch, git didn't let me at first. Once CI finishes, I will merge this.

I'll do a release for all packages later today.
