[webview_flutter_lwe] Update lightweight web engine to 1.4.1

[seungsoo47]

Reflects the latest starfish engine build: updated tizen/lib/*.so for aarch64, armel, i586, and x86_64, and LWEWebView.h now declares an optional preferMainThread parameter (defaults to true, no functional change to existing callers). Bumps package version to 0.5.2 and updates README/CHANGELOG accordingly.

This pull request updates the webview_flutter_lwe package to version 0.5.2. The changes include updating the lightweight web engine version to 1.4.1 and adding an optional preferMainThread parameter (defaulting to true) to the LWE::Initialize method in LWEWebView.h, along with its corresponding documentation. I have no feedback to provide.

This lightweight web engine update was made to address issues affecting google_maps_flutter. Verified with the google_maps_flutter integration tests, 5 runs each on the TV emulator and RPi4 — all passed, including cases that previously hung intermittently (testToggleInfoWindow, markerWithAssetMapBitmapCreate).
