This patch adds new Intel extended telemetry events for both ACL and
SCO/eSCO audio link quality reports.
For SCO/eSCO audio link quality report, it shows something like

Changes in v6:
- No changes in this patch. There are changes in patches 2/3 and 3/3.
Changes in v5:
- Fix two Make errors.
- Please also review Series-changes 3.
Changes in v4:
- Fix a Make error.
- Please also review Series-changes 3.
Changes in v3:
- Define the packed struct intel_ext_evt for the extended telemetry
event.
- Define the packed struct intel_tlv for the telemetry subevent.
- Define a new function intel_vendor_prefix_evt() to handle the new
vendor event type with a vendor prefix
0xff <length> <vendor_prefix> <subopcode> <data>
while intel_vendor_evt() handles the original vendor event type
0xff <length> <subopcode> <data>
- Add the vendor_prefix_evt_table table so that more subopcodes can be
added for the events with a vendor prefix.
- Move the event data buffer check after processing the current tlv.
- Fix typos.
Changes in v2:
- Perform size checks for tlv subevents.
- Fix the Make errors about qualifiers.

2.32.0.93.g670b81a890-goog
This patch adds a new UUID for the quality report experimental
feature. When reading the experimental features, it checks if
the new feature is supported by the controller and stores the
value in the quality_report_supported flag of the adapter.
The quality_report_supported flag could be used by the bluetoothd
to determine if the quality report feature can be enabled.

Changes in v6:
- Add support for decoding the new bqr UUID on src/shared/util.c.

2.32.0.93.g670b81a890-goog
This patch adds the "exp-bqr" command to btmgmt to enable/disable
the Bluetooth quality report (BQR).
---
Changes in v6:
- Remove the patch that adds btd_adapter_update_kernel_quality_report()
since no upstream code uses it per the previous review comment.
- Add this new patch to support the "exp-bqr" command in btmgmt to
enable/disable the Bluetooth quality report (BQR). This support is
to be consistent with other experimental features.
- Note that the bqr experimental feature is designed in the way that
it can be enabled/disabled at run time instead of at bluez daemon
launch time. And the default is to disable it in order to avoid the
overhead on the controller. Hence, it is not enabled through
btd_opts.experimental like what rpa_resolution_func() does.

Applied, thanks. Note that I did change the command name for exp-bqr
to exp-quality to make it more clear what is doing from the command
name itself.
