[csl] ensure SubMacis informed when CSL support changes (#7918)

Browse Source 
This commit changes `Mac::UpdateCsl()` to ensure we inform `SubMac`
and disable CSL when CSL support changes (e.g., device gets
detached). This ensures that `SubMac` internal variables (CSL period,
channel) are updated on a detach and if the device later attaches
again, we detect the change in CSL configuration and trigger the tx
of MLE Child Update Request.
