Require C++20 for the Windows plugin and Logcat crash fix (flet-dev#190)

* Add zipDirectoryPosix to create POSIX-compliant archives

Introduces the zipDirectoryPosix method to ensure archive entries use POSIX-style paths. Updates archive creation to use this method for better cross-platform compatibility.

* Await async calls in package file encoding

Changed calls to encoder.addFile and encoder.close to be awaited, ensuring proper handling of asynchronous file operations during package creation.

* Pin flet version in CI and update dependencies

CI workflow now pins the flet dependency to version 0.28.3 for all platforms. Updated .gitignore for macOS build artifacts, enabled GPU validation in Xcode scheme, and added secure restorable state support in AppDelegate. Dependency versions were updated in pubspec.lock and Podfile.lock, including upgrades to serious_python packages and other transitive dependencies.

* Enforce C++20 standard for plugin build

Added target_compile_features to require C++20 for the plugin. This ensures the code is compiled with C++20 features and compatibility.

* Normalize WINDIR path for bundled DLLs in CMake

Replaces backslashes with forward slashes in the WINDIR environment variable and updates DLL paths to use the normalized variable. This ensures consistent path formatting for bundled system libraries.

* Set argtypes and restype for __android_log_write

Configured ctypes argument and return types for liblog.__android_log_write to ensure correct interaction with the native Android logging library.

* Bump version to 0.9.9 and update changelogs

Release 0.9.9 for all serious_python packages. Adds zipDirectoryPosix for POSIX-compliant app archives on Windows, enforces C++20 standard for plugin build, normalizes WINDIR path for bundled DLLs in CMake, and fixes Logcat logging crash on some Android devices. Updates pubspecs and build files to reflect the new version.
