Build system and infrastructure
*******************************
* Added functionality for Link Time Optimization.
This change includes interrupt script generator rebuilding and adding following options:
- :kconfig:option:`CONFIG_ISR_TABLES_LOCAL_DECLARATION` Kconfig option:
LTO compatible interrupt tables parser,
- :kconfig:option:`CONFIG_LTO` Kconfig option: Enable Link Time Optimization.
Currently the LTO compatible interrupt tables parser is only supported by ARM architectures and
GCC compiler/linker.
See `pull request :github:`66392` for details.
* Dropped the ``COMPAT_INCLUDES`` option, it was unused since 3.0.
* Fixed an issue whereby board revision ``0`` did not include overlay files for that revision.
