/*
 * Check if low battery shutdown is needed
 *
 * This function checks if the system needs to shut down due to a critically low
 * battery level. It performs the following actions:
 *
 * 1. If Chrome EC is not supported, returns false (no shutdown needed).
 * 2. Uses static variables to cache the result and avoid repeated checks.
 * 3. If the battery level has not been checked yet:
 *    - Queries the Chrome EC to determine if the battery is below the critical threshold.
 *    - If the battery is below the threshold, sets the result to true.
 * 4. Returns the cached result.
