Subject: [PATCH 1/5] SignalAdaptor: add combinerType to signals, and use as
default combiner
As of it's now, we're downcasting from SignalBase to
Signal<SignalType> (which is the same type with
Signal<SignalType, LastValue<...>>) in its member functions.
The downcast is incorrect if its Combiner is NOT LastValue, fcitx5 will
run into undefined behaviours with this kind of casting.
In my local machine, this result in indeterminated value in
CheckUpdateResult, then fcitx5 will crash because of DBus' assertion.
When compiling with: -fsanitize=undefined, this problem is being
reported:
```
../src/lib/fcitx/../fcitx-utils/connectableobject.h:115:18: runtime error: downcast of address 0x559bd4a2a5b0 which does not point to an object of type 'Signal'

```
As a preparatory step, let's add combinerType into data structure for
Signal, and uses it as default combiner.

Subject: [PATCH 2/5] connectableobject: introduce
FCITX_DECLARE_SIGNAL_WITH_COMBINER
In order to correctly downcast SignalBase, in the next step,
we will switch all initialisation of SignalAdaptor to use
SignalType::combinerType.
Let's introduce a new macro to ease to initialisation of those
signals which employs custom combiner.
Arguably, the custom combiner is an implementation detail,
thus it'll be put in source files. Hence, the macro is intended
to be used outside of class declaration.

Subject: [PATCH 3/5] CheckUpdate: set combinerType in Signal data structure to
CheckUpdateResult
As of it's now, we're downcasting Signal data structure for CheckUpdate
from SignalBase to Signal<bool()> (which is the same type with
Signal<bool(), LastValue<bool>>) in SignalAdaptor member functions.
The downcast is incorrect because it's Signal<bool(), CheckUpdateResult>
instead, thus fcitx5 will run into undefined behaviours with this downcasting.
In my local machine, this result in indeterminated value in
CheckUpdateResult, then fcitx5 will crash because of DBus' assertion.

```
Let's downcast it into correct type by setting CheckUpdateResult as
combinerType.
