config: Add option to resolve keybinds by sym instead of code (#4851)

This commit adds the new configuration option 'resolve_binds_by_sym'
which can be set globally or per-device. It is off by default, which
preserves the current behavior.

This setting only affects the behavior of keybinds that are defined via
key symbols, not those defined via keycode. Binds defined by symbols
currently activate if the keycode pressed would generate the specified
symbol on the first layout specified in the input section.
If enabled, keys pressed on the relevant device will instead match
keybinds by the symbols they produce with their current layout.

Closes #1881.
