Bluetooth: Add reading of all local feature pages

Browse Source 
With the introduction of CSA4 there is now also a features page number 2
available. This patch increments the maximum supported page number to 2
and adds code for reading all available pages (as long as we have
support for them - indicated by HCI_MAX_PAGES).
