Subject: [PATCH] lv: build with LVGL 9.2

LVGL 9.2 declares lv_state_t as uint16_t, while bindgen emits the
LV_STATE_* values as u32. Accept any integer convertible to u32 in the
state helpers and cast it to lv_state_t.

lv_slider_set_value() takes an lv_anim_enable_t up to 9.2 and a bool
in later versions: pass the default value, that is "animation off"
for both.
