add warning or error when using bigint with floating point types

[Tragen]

Summary of the new feature

When you use bigint and add or multiply a floating point number, the result is wrong. I discussed it with the PowerShell team but they don't want to fix it. https://github.com/PowerShell/PowerShell/issues/21341

[double]$r = [bigint]5 * [double]1.5 Write-Host "bigint: $r" The result is "bigint: 5"

[double]$r = [bigint]5 + [double]1.5 Write-Host "bigint: $r" The result is "bigint: 6"

If you can add a meaningful rule that doesn't result in many false positives, happy for you to add such a rule and support you in that.
