Subject[PATCH v5 3/4] rust: add a Kconfig function to test for support of bindgen options
From: Asuna Yang <spriteovo@gmail.com>

Add a new `bindgen-backend-option` Kconfig function to test whether the
bindgen backend supports a given flag.

A subsequent commit will use this function to test for RISC-V extension
flags.
