Use wasm and js integration for unsupported systems

[sajjadarashhh]

Description

In our country people cant used latest technology utilities
For example we have customer with windows 7 and cpu dual core!
We cant force them to bought new system for our applications
We must be consider continued support them
In blazor must be used new features that check if browser is not compatible with blazor requirements like simd that our customers doesnt have problem with .net 7 but in .net 8 with this requirement many of them cant be used our system
We must be avoid to happen that problems when migrating from old version to new version

Reproduction Steps

Migrate from .net 7 to .net 8 and use windows 7

Expected behavior

Application is nit running

Actual behavior

Application must be check browser version and run specific version of that

Windows 7 support ended on January 14, 2020

You can use wasm-tools workload and recompille the application without SIMD and EH instructions.

• I'm describing basic how to here [browser] high level documentation of WASM features #89469
• detection is here [browser] detect SIMD and EH support #89387
• And compilation s being fixed here [wasm] Do not set -msimd128 in the default rsp #89433 and [wasm] Do not build mono libs with -msimd128 #89502
