For new advertising features, it will be important for userspace to
know the capabilities of the controller and kernel. If the controller
and kernel support extended advertising, we include flags indicating
hardware offloading support and support for setting tx power of adv
instances.

In the future, vendor-specific commands may allow the setting of tx
power in advertising instances, but for now this feature is only
marked available if extended advertising is supported.

This change is manually verified in userspace by ensuring the
advertising manager's supported_flags field is updated with new flags on
hatch chromebook (ext advertising supported).

Here we make sure we properly report the number of supported
advertising slots when we are using hardware offloading. If no
hardware offloading is available, we default this value to
HCI_MAX_ADV_INSTANCES for use in software rotation as before.

This change has been tested on kukui (no ext adv) and hatch (ext adv)
chromebooks by verifying "SupportedInstances" shows 5 (the default) and
6 (slots supported by controller), respectively.

Add functionality to disable and remove advertising instances,
and use that functionality in MGMT add/remove advertising calls.

Currently, advertising is globally-disabled, i.e. all instances are
disabled together, even if hardware offloading is available. This
patch adds functionality to disable and remove individual adv
instances, solving two issues:

1. On new advertisement registration, a global disable was done, and
then only the new instance was enabled. This meant only the newest
instance was actually enabled.

2. On advertisement removal, the structure was removed, but the instance
was never disabled or removed, which is incorrect with hardware offload
support.
