Validate levels in controls

[vojtapolasek]

Description:

• add a function which will check if a control does not include invalid level
• valid levels are defined in the policy, any other levels are invalid

Rationale:

Inspired while verifying #11417

Review Hints:

• choose a policy which has defined levels, change a control to contain undefined level and build any product
• choose a policy which does not use level and define a level for a particular control, build any product

@Mab879 I think I fixed everything I could. I consider extracting code from controls.py to satisfy the requirement on number of lines as out of scope.
