chore(debug): Implement core dump handling

[Slider0007]

Implement coredump handler and WebUI interface to easily view or download dump files for debugging purposes (Offline software exception evaluation) --> More Info: ESP-IDF documenation

• Update partition table
• Implement REST API to control core dump handling -> REST API coredump
• Implement WebUI controls in System > System Info > Section Build
  • Show: Show dump backtrace summary
  • Save: Download core dump file to evaluate offline -> Howto
  • Clear: Format coredump partition to delete existing core dump data (NOTE: partition will be erased automatically after successful OTA update to ensure a clean start)
    
    An exception info is available:

⚠️⚠️⚠️ The partition table needs to be updated ⚠️⚠️⚠️
A new parition (coredump) is needed. New partition is added to end of existing partitions to not relocate them. Therefore an update of only the partition table should be enough. If partition is missing, functionality is not available, but it doesn't have any negative impact to flow processing.

Howto: Flash partitions.bin (part of firmware zip package) to MCU address 0x8000 using your favorite flash tool. More info
