Add a new --check-missing-config-prefix check that looks for references
like

    #if MACRO
    #if(n)def MACRO
    defined(MACRO)
    IS_ENABLED(MACRO)

where MACRO is the name of a defined Kconfig symbol but doesn't have a
CONFIG_ prefix. Could be a typo.

Skip MACRO if it is #define'd somewhere, even if it looks like a Kconfig
symbol.

Found e.g. https://github.com/zephyrproject-rtos/zephyr/pull/22195.

Piggyback skipping binary files when grepping for Kconfig symbol
references.
