ESP-IDF provides a more efficient way of handling and combining
multi-configurations for a project than the way currently used:
Build profiles.
So I switched to this method instead of providing the sdkconfig.defaults.*
files manually. This reduced the number of sdkconfig.defaults.* files
as well as the configuration parameters defined in them.
Refs #1085
Specific `_*all` and `_*all_with` functions were implemented to make
the API more concise and clean, and to replace the use of
`RELAY_CHN_ID_ALL`, which caused confusion within the API.
Refs #1085
- Introduced configuration options for enabling run limits in Kconfig.
- Added APIs to get and set run limits for individual relay channels.
- Implemented run limit timer functionality to automatically stop channels.
- Updated NVS handling to store and retrieve run limit values.

Closes #1080
- Added new utility script run_tests_all_cfgs.sh to run tests for all configurations and with test tag support.
- Updated run_tests.sh to add the new test tag for NVS unit tests.
