samples: modules: lvgl: fix integer overflow

`lv_task_handler()` returns a `uint32_t`, but `k_msleep` takes a
`int32_t`.

If no timer exists, `lv_task_handler()` returns `UINT32_MAX` to indicate
that we should wait forever. However, this gets auto-cast to `-1`,
indicating to `k_msleep` to not wait at all, creating a busy loop.

Hence, a clamping to `[0, INT32_MAX]` is required.

samples: lvgl: sensor: Add LVGL sample for real-time sensor data chart

This adds a new sample for LVGL that displays a real-time chart for
accelerometer data acquired from &accel0 sensor.

This also adds the appropriate overlays so that the sample can also run
on native POSIX and native sim using emulated BMI160.
