Add GPIO LED states, mode

Pull request overview

Extends the gpio-leds device-tree driver with two new properties: default-state (off/on/keep) and osiris,output-mode (push-pull/open-drain). The dtgen codegen now emits two new enums and registry fields, the kernel LED driver consumes them at init time, and the STM32L4 GPIO HAL gains an open-drain configure helper plus a clock-enable helper used to safely read a pre-init pin.

Changes:

• Generate LedDefaultState / LedOutputMode enums and registry fields from device-tree properties (xtasks/crates/dtgen/src/codegen/led.rs).
• Wire the new properties into LED init: pick initial level from default-state, choose push-pull vs open-drain configure call, and log the mode (src/drivers/led.rs).
• Add gpio_configure_output_od and gpio_clock_enable to the STM32L4 HAL plus matching native Rust wrappers and stub-side enum/struct fields.
