core: hle: kernel: Updated implementation of svcSetHeapSize.

Browse source 
- Updates our svcSetHeapSize with latest HOS, furthermore allowing heap size to properly be extended/shrunk.
- Validated with tests https://github.com/Atmosphere-NX/Atmosphere/blob/master/tests/TestSvc/source/test_set_heap_size.cpp.
