CONFIG_ESP_SYSTEM_PANIC_GDBSTUB suppress CONFIG_ESP_COREDUMP_ENABLE in panic.c but the menuconfig does not specify the conflict (IDFGH-8567)

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

I just realized that when CONFIG_ESP_SYSTEM_PANIC_GDBSTUB is checked (Under Component config → ESP System Settings → Panic handler behaviour) the core-dump-to-flash did not generate any data.

esp-idf/components/esp_system/panic.c

Lines 348 to 349 in e9d7340

	#else
	#if CONFIG_ESP_COREDUMP_ENABLE

Clearly, core dump is not enabled when GDB Stub is in use. I think those two options should be linked with Kconfig dependencies.

Thanks for reporting this.

Actually, I cant think of a good reason why you shouldnt be allowed to use both. We have merged an internal MR to allow these features to be used together now.
