Bluetooth: Kconfig: Update buffer sizes for advertising extension

Browse source 
Update buffer sizes needed when advertising extensions is enabled. Since
BT_RX_BUF_LEN is used for the HCI command as well we need to fit the
full 255 bytes of the Set Extended Advertising Data or Scan Response
Data plus the 3 byte header of an HCI command.

For the discardable buffer size we need to fit the LE Extended
Advertising Report event, which can be a maximum of 255 bytes plus the
2 byte header of an HCI event.
