lib-builder: review and extract non-chip-specific sdkconfig options into a common sdkconfig file #6465
Description
In lib-builder, some of the sdkconfig options which are not chip-specific have different values for different chip targets.
This leads to weird behavior when some non-chip-specific features behave differently on different chips (e.g. #6187)
The task is to review the chip-specific sdkconfig files and extract all non-chip-specific options into a common file.
