sdbus++: events: create json for events

Create JSON for the events containing their metadata and leverage that
as the "message" portion of the `sd_bus_error`. This will allow
unpacking the message on a client side back to the original exception.

Tested:
```
$ busctl --user call net.poettering.Calculator /net/poettering/calculator net.poettering.Calculator Divide xx 5 0
Call failed: {"net.poettering.Calculator.DivisionByZero":{"FOO":"unused"}}

build: move python setuptools for future non-autotools

The current setup.py.in is an autotools-generated setuptools-like
install script. When building the python-only module, we don't
need the complexity of autotools, but the well-supported python
install behavior is for a script named 'setup.py'. In order to
facilitiate creating a native setuptools setup.py, move the autotools
one to a different name. This allows both to live in parallel for a
bit.

Emit adding/removing interfaces for object server

The object server currently either creats the objects and interfaces, or
defer the signal by not adding objects.

In practice, we have situations that the code would like to add
interfaces to an existing object, and it's not supported, or needs
tricky code to workaround.
Exmaples:
https://gerrit.openbmc-project.xyz/c/openbmc/phosphor-bmc-code-mgmt/+/5820
https://gerrit.openbmc-project.xyz/c/openbmc/openpower-pnor-code-mgmt/+/5346

This commit adds the support by:
1. Adding emit_added() in interface.hpp and the generated server.hpp
2. Adding a enum class in object's constructor to indicate which action
to do, to create the object, or adding the interface, or defer signal
as before.

So the user of object<> could pass `action::emit_interface_added` to the
constructor to tell the object server *only* emit interface added to
DBus, without emitting object added.
The previous code stays the same behavior:
* If `true` is passed in object's constructor, it defers emitting object
added signal;
* If no extra parameter is passed in object's constructor, it emits
object added signal as before.

Tested: 1. Make sure the openbmc builds fine with
https://gerrit.openbmc-project.xyz/c/openbmc/phosphor-logging/+/25089
because phosphor-logging uses its own server.hpp for interface, the
above patch removes that.
2. Manually write a small service to verify the interfaces are
added and removed by using the `emit_interface_added` action.
3. Added the unit test cases for object.hpp to check the
ctor/dtor with different actions.
