ActiveModeManager: Method to check if STA/AP concurrency is supported

Instead of plumbing this feature flag directly from the driver, use the
interface combination exposed by HAL to determine if STA/AP concurrency
is supported. This method is more future proof than a static
flag retrieved from the driver because for devices which might support
STA + AP || STA + STA, this method can return false if 2 STA's are
already up (so cannot support STA + AP unless it brings down one of the
STA's).
