Ivan Grokhotkov 73b30af2b3 confgen.py: don't output compatibility definitions for options which are not defined
For example, if a renamed option CONFIG_NEW is a bool with value "n", kconfiglib will not generate a define for it in the Kconfig file. The define (#define CONFIG_NEW 1) will only be generated if the option is "y" or "m".
However the compatibility definition was always generated: #define CONFIG_OLD CONFIG_NEW. This broke the #ifdef checks which depended on the old option names.

Bootloader Support Component
============================

Overview
--------

"Bootloader support" contains APIs which are used by the bootloader but are also needed for the main app.

Code in this component needs to be aware of being executed in a bootloader environment (no RTOS available, BOOTLOADER_BUILD macro set) or in an esp-idf app environment (RTOS running, need locking support.)
