The HCI transport implemented by an application using the HCI raw interface may have its own buffer headroom requirements. Currently the available headroom gets completely determined by the selected HCI driver. E.g. most of the time this is the native controller driver which doesn't reserve any headroom at all. To cover for the needs of HCI raw users, add a new Kconfig variable for the apps to set to whatever they need. Correspondingly, use the maximum of the HCI driver and HCI raw headroom requirements for the buffer pool definitions and the headroom initializations.
