Rename ESP32 system_info/1 memory keys to match available STM32 keys

Renames ESP32 system_info/1 heap memory keys from esp32_free_heap_size to atomvm_free_heap_size and
esp32_minimum_free_size to atomvm_minimum_free_size to match newly added STM32 memory keys.

 ### Changed
 
 - Removed `externalterm_to_term_copy` added in [0.6.5] and introduced flags to `externalterm_to_term` to perform copy.
+- Renamed ESP32 `system_info/1` memory keys from `esp32_free_heap_size` to `atomvm_free_heap_size` and
+`esp32_minimum_free_size` to `atomvm_minimum_free_size` to match newly added STM32 memory keys.
