Detect bad properties in profile specific files

Throw an `InvalidConfigDataPropertyException` if bad properties are
detected in profile specific files. The following properties will now
trigger an exception if used in a profile specific file:

	`spring.profiles.include`
	`spring.profiles.active`
	`spring.profiles.default`
	`spring.config.activate.on-profile`
	`spring.profiles`

Prior to this commit, profile based properties in a profile specific
file would be silently ignored, making them hard to find.

Fixes gh-24733
