Helper Text Created

[EduVencovsky]

Created MatHelperText component following material design guide lines.

The reason I created this is because it would be good to have a standard component and remove some logic from MatTextField.

This will also enable user to use it if they need for some special reason.

And now I have a few question for the contributors for further improvements.

• As I created a parameter called CharacterCount, should I add a parameter in the MatTextField for that too?
• What do you guys think about creating a component for each different part of the MatTextField just like react's material version, where they have 6 components that can compose TextField component? (You can see another mention of this here)
• While looking at the material design docs and the code of MatBlazor, I realized that the HelperText of TextField and Select is different, so I didn't implement it and now we need to make a decision on how to handle this diference.
  • Create another component for the Select's HelperText
  • Create a parameter for HelperText that will say to use the Select's HelperText
  • Create parameters that can be used to make changes to look like Select's HelperText or TextField's HelperText (e.g. create a parameter for margin)

Hope you guys enjoy, thanks for everything!

I think this is good start, later someone can reuse this component in other parts of MatBlazor components.

Thank you, @EduVencovsky !
