[python/mdns] Add "resolve" command for operational discovery (projec…

…t-chip#5025)

* [mdns] Add Resolver interface

Expose the mDNS resolver functionality implemented for
Avahi/Linux using a new Resolver interface.

* [mdns] Fix build with chip_mdns_advertiser="platform"

* [mdns/python] Add command to resolve address of a CHIP device

Add DeviceAddressUpdater class which updates device
addresses in the device controller based on responses from
mDNS resolver. A result of an update/resolution request
can be passed to an optional DeviceAddressUpdateDelegate.

Add "resolve <fabricid> <nodeid>" command to the Python
CHIP controller. Usage:
1. Build CHIP with chip_mdns_advertiser="platform" argument.
2. Start Python CHIP controller.
3. Pair a CHIP device using "connect -ble" command.
4. Resolve the node ID using "resolve <fabricid> <nodeid>".

Note that Thread devices currently don't support the DNS-SD
service registration, but one can still test the new command
by registering the necessary services manually, e.g.

avahi-publish-address test-host.local. fd11:22::1 &
avahi-publish-publish-service -H test-host.local \
    <fabricid-hex>-<nodeid-hex> _chip._tcp 11097

* [mdns] Fix improper global object initialization order.

On Linux, DiscoveryImplPlatform constructor refers to
MdnsAvahi global object which may not yet be initialized.
Some refactoring in the code is required to come up with
a better solution, but for now make sure that
DiscoveryImplPlatform is not initialized prior to MdnsAvahi.

* [mdns] Apply code review comments

Also, fix updating the device address in the device
controller as previously the connection state wasn't
updated.

Start a script-friendly CHIP REPL for python (project-chip#4696)

* Define a chip-repl script that is intended to provide an interactive console against the python interfaces that chip provides

* Make GetAdapters work on chip repl

* Restyle fixes

Send current IP address during network provisioning (project-chip#4591)

[nrfconnect] Fix compilation warnings and turn on -Werror for examples (

project-chip#4528)

Rename BIT/BYTE_x macros from the ember code to fix the BIT
macro redeclaration (the same macro is provided by Zephyr).
