Subject: [PATCH] Fix compat tests due to esp-idf moving include files

Peripheral register definitions were moved to a new directory
inside the ESP-IDF: components/soc/{cpu_type}/register.

This change caused our compat tests to fail because they
depended on predefined register constants.

This commit resolves the issue by adding the new directory to
GCC's include search path using the -I option.

Additionally, all header files in this new directory are now
added to the DefinesDB for the compat tests with RTC macros.

Fixes #100.
