Cached designtime info for encountered sources.

The designtime information is collected only for files named '*.designtime.js'.
It is stored in this map keyed by the corresponding module name (e.g. 'sap/m/designtime/Button.designtime').
Only after all files have been parsed, the collected information can be associated with runtime metadata
that refers to that designtime module name.
