[wxwidgets] Update to 3.3.3

[Emily Mabrey (emabrey)]

Update wxwidgets from 3.3.1 to 3.3.3. Patches are refreshed against the new line context. Two hunks of install-layout.patch (create_symlink -> copy in install.cmake and utils/CMakeLists.txt) are dropped in favor of the new upstream option wxBUILD_INSTALL_USE_SYMLINK=OFF, which the port now sets. Lexilla submodule is bumped to the sha paired with 3.3.3, and vcpkg_cmake_config_fixup(CONFIG_PATH ...) moves to lib/cmake/wxWidgets-3.3 to match the versioned install layout wxWidgets 3.3 now emits.

Verified locally with a full vcpkg install wxwidgets:x64-windows build (15 min, dbg + rel, post-build validation passed).

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version, or no changes were necessary.
• Any fixed CI baseline and CI feature baseline entries are removed from that file, or no entries needed to be changed.
• All patch files in the port are applied and succeed.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Exactly one version is added in each modified versions file.

CI turned up two failures the local x64-windows verification didn't catch. Three follow-ups:

Depend on libsecret for secretstore on Linux. 3.3.3 promoted "libsecret missing" from a silent-disable to a hard configure error under wxUSE_SECRETSTORE=ON. Adds the dep behind the same platform gate the other Linux-only feature deps use.

Strip target-name leaks from wx-config -- separate arm64_osx / x64_linux issue. wx_get_dependencies writes raw target names into wx-config's LIBS when an imported dep has no IMPORTED_LOCATION, which is what vcpkg's header-only NanoSVG looks like on Linux and macOS. Downstream then sees -lNanoSVG::nanosvg and target_link_libraries chokes. Stripped post-install; the port's vcpkg-cmake-wrapper.cmake already re-adds the real targets for static. Upstream fix targeted for 3.3.4 (wxWidgets/wxWidgets#23373).

Add LIBSECRET_LIBRARY_DIRS to wxbase link deps, as once libsecret was installed, wxrc-3.3 failed to link with "cannot find -lgcrypt / -lgpg-error". FindLIBSECRET.cmake populates both LIBSECRET_LIBRARIES and LIBSECRET_LIBRARY_DIRS via pkg_check_modules, but base/CMakeLists.txt only consumed the former. Adds a wx_lib_link_directories on the -L dirs so libsecret's transitive static deps are actually findable at link time.
