fix: qtdeclarative metatypes resolution via extended dep sysroot symlinks

The Qt6SvgTargets.cmake config contains absolute paths to qtsvg's own
sysroot/metatypes/ for INTERFACE_SOURCES. When the cookbook cleans
qtsvg's sysroot between recipe builds, these paths dangle and cause
CMake Generate to fail.

Extend redbear_qt_ensure_dep_sysroots to create symlinks for ALL Qt
directories (metatypes, plugins, mkspecs, modules, qml) — not just
include and lib. Add the call to qtdeclarative's recipe (was missing).
