bluetooth: host: Specify controller in BT_HCI_TX_STACK_SIZE defaults

Browse source 
By specifying the controller directly when selecting the default
BT_HCI_TX_STACK_SIZE, an external controller may rely on the final
default value when none of the in-tree controllers are used.

The value is increased to 1024 to accomodate the current worst-case
stack size.
