Generate kconfig variables from SoC caps headers

gen_soc_caps_config.py is used to turn defines from soc_caps.h into kconfig variables that can be included and used both in menuconfig and during the build process

The script will automatically run as part of the pre-commit hook if any of the soc_caps related files have been modified.

To run it manually, navigate to ${IDF_PATH} and execute:

`python tools/gen_soc_caps_kconfig/gen_soc_caps_kconfig.py -d 'components/soc/*/include/soc/'`

The results are kconfig.soc_caps.in-files containing the bool/int/hex/string values defined in the soc_caps.h file.

This target specific kconfig file is then imported in $IDF_PATH/Kconfig.

Tips

Defines that are 0 or 1 will automatically be interpreted as Booleans. If it's necessary to have this variable available as an integer instead then this can be achieved by adding an U suffix when defining it. E.g:

`#define SOC_I2C_NUM (1U)`

The script is not able to evaluate expressions, e.g X*Y. If you need a variable to be available in kconfig it needs to be a simple assignment expression.
