Subject: [PATCH v2] Bluetooth: btrtl: Set MSFT_EXT_ADDRESS_FILTER quirk for RTL8852B

Set HCI_QUIRK_USE_MSFT_EXT_ADDRESS_FILTER quirk for RTL8852B.

The quirk to support tracking multiple devices concurrently.
Commit 9e14606d8f38 ("Bluetooth: msft: Extended monitor tracking by
address filter")

With this setting, when a pattern monitor detects the device, this
feature issues an address monitor for tracking that device. Let
pattern monitor can keep monitor new devices.

Verified by Chromebook and Raspberry Pis.
