[FIR, IR] Fix name mangling for functions with context receivers

- Mangled names of property accessors now include context receiver
  types of the corresponding property when computed from FIR.
- Context receivers are now supported when computing mangled names
  from IR
- IrBasedDescriptors now account for context receivers
