heap: add check for usage of flash content from iram

Browse Source 
this commits:
- adds build-time test to check that no call to flash regions are done from IRAM functions

- resolves problems related to IRAM function using content in flash memory

- update heap_caps_alloc_failed to use a default function name in DRAM
  when necessary instead of creating a function name variable in DRAM for
  each call of heap_caps_alloc_failed. This allows to save some extra bytes
  in RAM.
