drm_hwcomposer: CI: Pull headers from the AOSPv11
The goal is to check compilation and clang-tidy at CI stage.
For both compile and tidy all dependent headers are required.
Compilation and tidy-check enabled by the next commit.
Done by invoking the following bash commands:
cp system/core/libcutils/include/cutils/native_handle.h \
system/core/libcutils/include/cutils/compiler.h \
system/core/libcutils/include/cutils/trace.h \
external/drm_hwcomposer/.ci/android_headers/cutils/
cp external/libdrm/android/gralloc_handle.h \
external/drm_hwcomposer/.ci/android_headers/gralloc_handle.h
cp hardware/libhardware/include/hardware/gralloc.h \
hardware/libhardware/include/hardware/hardware.h \
hardware/libhardware/include/hardware/hwcomposer.h \
hardware/libhardware/include/hardware/hwcomposer2.h \
hardware/libhardware/include/hardware/hwcomposer_defs.h \
external/drm_hwcomposer/.ci/android_headers/hardware/
cp system/core/libsync/include/sync/sync.h \
external/drm_hwcomposer/.ci/android_headers/sync/sync.h
cp system/core/libsync/include/ndk/sync.h \
external/drm_hwcomposer/.ci/android_headers/ndk/sync.h
cp system/core/libsystem/include/system/graphics-base-v1.0.h \

system/core/libsystem/include/system/graphics-sw.h \
system/core/libsystem/include/system/graphics.h \
external/drm_hwcomposer/.ci/android_headers/system/
cp frameworks/native/libs/ui/include/ui/GraphicBuffer.h \
external/drm_hwcomposer/.ci/android_headers/ui/GraphicBuffer.h
