Rule Idea: Warn on `[xml](Get-Content <File>)` pattern

Summary of the new feature

Warn on Pattern: [xml](Get-Content <File>)
Suggest Pattern: $a = [xml]::new(); $a.Load(<File>)

This pattern is currently in wide use, but it has some problems and should be discouraged.

1. This pattern, due to using Get-Content, has problems if the (perfectly valid) xml file being parsed is not utf8 encoded. See: https://github.com/PowerShell/PowerShell/issues/14505 & https://stackoverflow.com/questions/65263942/how-to-load-or-read-an-xml-file-using-convertto-xml-and-select-xml/65264118#65264118

2. This pattern is very inefficient. I know that PSSA does not generally worry about this - but since the encoding issue above exists, feels worth it to mention. Testing against a ~1mb file shows [xml](Get-Content <File>) as ~12x slower, and against a 170mb file as 22x slower (loading took 46 seconds!).

What is the latest version of PSScriptAnalyzer at the point of writing
PSSA 1.19.1

Powershell Versions
This currently affects both Windows Powershell 5.1 and Powershell 7.

El issue tiene como objetivo PSScriptAnalyzer y el patrón de PowerShell [xml](Get-Content <File>). Empieza por encontrar las implementaciones de reglas y las pruebas existentes del analizador para diagnósticos basados en patrones; se considera terminado cuando se advierta sobre el patrón y la forma sugerida de cargar XML se informe de manera coherente en Windows PowerShell 5.1 y PowerShell 7.
