This commit extends fa33382c7f74 ("HID: apple: Properly handle function
keys on Keychron keyboards") by adding an array of known non-Apple
keyboards' device names, and the function apple_is_non_apple_keyboard()
to identify and create exception for them.

V4 -> V5: Add Varmilo keyboards' name "AONE" to the exception list
V3 -> V4: Remove unnecessary strlen()
