bump texture plugins with adversarial-review fixes

flutter_texture_rgba_renderer 7932bf9: linux double-free/terminate-UAF
fixes, exported GetConsumed (was invisible to dlsym under hidden
visibility - the watchdog was silently disabled on Linux), C++14
shared_timed_mutex; macos autoreleasepool + failed-registration guard.
flutter_gpu_texture_renderer 208619e: rendering_ no longer sticks true
before the first populate; honest GetConsumed semantics (descriptor
fetches; EGL bind failure still advances it) - noted at the gpu
watchdog call site.
