[TASK] FormEngine: Replace placeholder resolving with a data provider

Resolving of placeholder for field types text and input has been moved
from the element rendering into the form data providers. The data
provider approach allows reuse of existing providers and data groups and
reduces the amount of database queries by having access to previously
parsed data.
