Config-flow for DLNA-DMR integration (#55267)

* Modernize dlna_dmr component: configflow, test, types

* Support config-flow with ssdp discovery
* Add unit tests
* Enforce strict typing
* Gracefully handle network devices (dis)appearing

* Fix Aiohttp mock response headers type to match actual response class

* Fixes from code review

* Fixes from code review

* Import device config in flow if unavailable at hass start

* Support SSDP advertisements

* Ignore bad BOOTID, fix ssdp:byebye handling

* Only listen for events on interface connected to device

* Release all listeners when entities are removed

* Warn about deprecated dlna_dmr configuration

* Use sublogger for dlna_dmr.config_flow for easier filtering

* Tests for dlna_dmr.data module

* Rewrite DMR tests for HA style

* Fix DMR strings: "Digital Media *Renderer*"

* Update DMR entity state and device info when changed

* Replace deprecated async_upnp_client State with TransportState

* supported_features are dynamic, based on current device state

* Cleanup fully when subscription fails

* Log warnings when device connection fails unexpectedly

* Set PARALLEL_UPDATES to unlimited

* Fix spelling

* Fixes from code review

* Simplify has & can checks to just can, which includes has

* Treat transitioning state as playing (not idle) to reduce UI jerking

* Test if device is usable

* Handle ssdp:update messages properly

* Fix _remove_ssdp_callbacks being shared by all DlnaDmrEntity instances

* Fix tests for transitioning state

* Mock DmrDevice.is_profile_device (added to support embedded devices)

* Use ST & NT SSDP headers to find DMR devices, not deviceType

The deviceType is extracted from the device's description XML, and will not
be what we want when dealing with embedded devices.

* Use UDN from SSDP headers, not device description, as unique_id

The SSDP headers have the UDN of the embedded device that we're interested
in, whereas the device description (`ATTR_UPNP_UDN`) field will always be
for the root device.

* Fix DMR string English localization

* Test config flow with UDN from SSDP headers

* Bump async-upnp-client==0.22.1, fix flake8 error

* fix test for remapping

* DMR HA Device connections based on root and embedded UDN

* DmrDevice's UpnpDevice is now named profile_device

* Use device type from SSDP headers, not device description

* Mark dlna_dmr constants as Final

* Use embedded device UDN and type for unique ID when connected via URL

* More informative connection error messages

* Also match SSDP messages on NT headers

The NT header is to ssdp:alive messages what ST is to M-SEARCH responses.

* Bump async-upnp-client==0.22.2

* fix merge

* Bump async-upnp-client==0.22.3
