Subject: [Keymap] Display logo for caps lock indication on crkbd using old
 OLED driver (#7535)

* Display logo for caps lock indication on crkbd using old OLED driver

* Add emacs read-only mode file variable to generated files

* use LTO_ENABLE instead of EXTRAFLAGS

This enables the same option, and disables action_macros, and action_functions, both of which seem to break when LTO is enabled. And this is a lot simpler to use.
