Enable mouse cursors for TV devices

[swift-kim]

Fixes flutter-tizen/flutter-tizen#364.

• Add the EnableCursor method to TizenWindowEcoreWl2 which is implemented for TV devices only. The method uses dlopen to invoke the Cursor_Set_Config function in libvd-win-util.so.
• Style the code in SetTizenPolicyNotificationLevel in a consistent way.

dlopen and dlsym should not affect the performance (launching time) noticeably.

All the changes in this PR look good to me., but unfortunately, the mouse cursor doesn't show up on my TV.
Is there anything else we need to enable cursor?

//TIZEN/[MAIN]/[ONEPROD_Prj]/[INT]/COMMON/Profile/platform/framework/web/chromium-efl/wrt/src/browser/tv/wrt_native_window_tv.cc
WRTNativeWindowTV::CreateMouseCursor(Evas_Object* window)
CreateMouseCursor API contains all the code for the mouse cursor.

I found the some different to get "surface" between your code and my code.
(Is this the cause?)

Would you like to test by forcibly enabling the mouse cursor?
vconftool set -t bool memory/window_system/input/force_enable_cursor 1 -f

[yman-son]

dlclose doesn't need a call?

[swift-kim]

You're right. I'll fix.

[yman-son]

There is also a call of CursorModule_Finalize() in my code~

[swift-kim]

Fixed in 58adc7d.

vconftool set -t bool memory/window_system/input/force_enable_cursor 1 -f

I've been using this for a long time :)

@yman-son Our embedder code doesn't rely on the Ecore Evas API but directly creates and manages Ecore Wl2 window instances. Thus it already has a reference to the window handle and a wayland surface can be retrieved from it.

vconftool set -t bool memory/window_system/input/force_enable_cursor 1 -f

I can find log in dlog when cursor setting is successful.
Please check it.

@yman-son We can also see the log message you mentioned when the app launches.

But the cursor only appears on the screen when force_enable_cursor is set to true. We want to enable the cursor even if the value is set to false (the default value). Are you testing with force_enable_cursor turned off?

I test vconf in false state for WRT. (ex : tving)
I will check if there is a code that disables the mouse cursor for .NET application in AUL or context-manager.

I applied the changed code with Kim's help and conducted the test on the TV.
the mouse cursor worked normally when vconf was disabled.
I don't know what environmental differences cause this kind of problem.
But what is certain is that the code of this PR is normal.
