The data model generation fails if a property name uses a C# reserved keyword

[mlqn]

Description of the bug

The data model generation fails if a property name uses a C# reserved keyword (e.g., new, private, class, if, enum, etc).
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/

We can probably reuse part of the validation mechanism of the data model name (see: #14049).

Steps To Reproduce

Property name

data-model-property-error.mov

Data model name (works as expected)
