m17n integration

[PoneyClairDeLune]

描述你请求的功能是否和问题有关 / Is your feature request related to a problem? Please describe.
fcitx5-android currently lacks m17n support. Supporting m17n allows importing the already vast repository of m17n schemas, skyrocketing the total sum of the languages supported.

tbh I really hope this project would beat Gboard soon

描述解决方案 / Describe the solution you'd like
Add support for m17n.

描述替代方案 / Describe alternatives you've considered
There doesn't seem to be an alternative way to use m17n databases/schemas on fcitx5-android.

m17n requires many native libraries and would be a hassle to build on Android. If anybody would like to spend their time to deal with it (including reproducible build), I appreciate it, but I just don't have enough time.

And I doubt the quality of "input methods" implemented in m17n, since their Chinese input methods are "not a good solution" .

Not exactly sure about Chinese, but their other schemas could be used quite well.

@rocka m17n is commonly used for many Indian languages

m17n bindings are very good for Indian scripts, and there is a wide number of scripts supported.

There is already support for Chinese so this should not be blocked by Chinese m17n bindings.

There is no good Indian script keyboard on Android. Due to it, the lack of m17n on Android is annoying at times. Since m17n is only on Linux, most people don't even know such good way to transliterate exists, and hence do not feel the "lack" of it.

Hence, if this keyboard adds m17n support, it would be great for many users - Indian or not.

It also provides a standard way of specifying input method, so anyone can create a descriptor file which could be allowed to be imported into the keyboard.
