Allow to define the build profile at maven plugin level

[essobedo]

fixes #13341

Motivation

We would like to have the ability to define the build profile directly in the configuration of the plugin or via a project property.

Modifications:

• Checks if the project property quarkus.profile has been set and if so uses this value as build profile if and only if it has not already been set using the corresponding system property or environment variable.

We've been avoiding adding mojo parameters that duplicate application properties. E.g. the uberJar mojo parameter has recently been removed. Which I personally wasn't sure about but that was the decision and we should probably stick to it for other config options as well. Unless the users start pushing hard for it.
In this specific case though, I guess you could remove the parameter and simply look for the project property with that name. I think it'd be an acceptable compromise. WDYT? And thanks for another contribution @essobedo

@aloubyansky Hi I was not aware of this rule, indeed it makes sense to remove it, so here is a new version with only the support of project property
