Fix VM Address mask (#8440)

Browse Source 
* Fix VM Address mask

Adjust VM Address mask to allow up to 8M Byte parts.
Allow for free heap size values over 64K
  ESP.getHeapStats(, uint32_t,)
  uint32_t getMaxFreeBlockSize();

* Fix example

* Update MockEsp.cpp for uint32_t on EspClass::getMaxFreeBlockSize()

* Added comment about heap size limitation and static_assert to verify.
Updated boards.txt to show correct External memory size and Heap size.
