[video_player_avplay] Support multi TizenOS version

[JSUYA]

#873

• Updated the guide in the readme.
• Modified exception messages that occurred based on the api-version and platform version. Going forward, compatibility is supported for OS versions 6.5 to 9.0, enabling distribution as a single package(6.0 and 10.0 should be distributed separately).

(This PR has been checked on TizenOS version 9.0.)

Please review whether the README's guide is appropriate.
(https://github.com/JSUYA/plugins/tree/avplay_multios/packages/video_player_avplay)
I have verified this PR on Tizen 9.0 TV. If you have other versions of TV devices, please test them.

I set api-version to 8.0 and 9.0，then compiled the tpk package and ran it, I got a same crash log:

Because the sample app doesn't include plusplayer libs

Oh... In my test, the so files were packaging correctly... I think I must have misunderstood something. I'll check.

I found that only the so file under apiVersion is copied in flutter-tizen/lib/build_targets/plugins.dart:245.
I will find other way.

I will find other way.

flutter-tizen/flutter-tizen#662
In native plugin builds, only the SO files in lib, lib/arch, and lib/arch/apiVersion are packaged together.
Therefore, I added a way that allows plugins to add user paths(USER_LIB_PATH).

However, I'm not sure if this is the best approach. If you have a better idea, please share it.

6.5, 7.0, 8.0, 9.0 libs are all identical (libslive-jsoncpp.so appears to differ per version), so existing libs were not modified.
Only the exception condition in _checkPlatformAndApiVersion() was modified.

The task of removing duplicate libs is deferred to the next step.
