[FIR] Fix scope of Java classes that inherit multiple properties with the same name

Use the receiver and context receiver types in addition to the property
name as cache keys for the synthetic property generation.
Also, fix logic that searches for accessor overrides by comparing
receiver and context receiver types.
Finally, let synthetic properties delegate their receiverParameter and
contextReceivers to their accessors.
