keymap: Add parameter `latchOnPress` for LatchMods() Some keyboard layouts use `ISO_Level3_Latch` or `ISO_Level5_Latch` to define “built-in” dead keys: - they do not rely on the installation of custom Compose file; - they do not clash with other layouts. However, layout projects usually want the exact same behavior on all OS, but the XKB latch behavior (often misunderstood) also acts as a *set* modifier, which is not expected. The usual behavior of a dead key on Linux, macOS and Windows is: - latch on press; - deactivate as soon as another (non-modifier) key is pressed. Added the parameter `latchOnPress` to `LatchMods()` to enable the aforementioned behavior. As it is incompatible with X11, this feature is available only using the keymap text format v2.
