Update git submodules

* Update ndk from branch 'ndk-release-r19'
  to 4009daf2819776a9cc273050f16976379f7c85f5
  - Merge "Disable multithreaded linking for Windows LLD." into ndk-release-r19
  - Disable multithreaded linking for Windows LLD.
    
    This only affects ndk-build because CMake can't currently check if it
    is using LLD since our toolchain file has finished running by the
    time the user can add ldflags.
    
    Not enabling this with standalone toolchains since we can't enable it
    for the built in toolchains without recompiling Clang and those are
    supposed to match. Will disable in the driver in a follow up if a
    workaround is not found.
    
    Test: ./checkbuild.py
