Add build flag for a "dma_buf" Android build Add angle_android_dma_buf gn flag, defaulting to false. When enabled: - Enables a "linux-like" build of ANGLE while using the Android toolchain, by making the OS detection logic define PLATFORM_OS_POSIX but not PLATFORM_OS_ANDROID. - Makes ANGLE default to using Vulkan backend, and - Enables DMA-BUF based external image support. This allows setting up GL framebuffers backed by DMA-BUFs, enabling rendering without full Android graphics stack. See the bug for details. Bug: b/353262025 Test: treehugger Test: Build the entire CL chain with the new Soong config flag enabled Test: run the system, attach debugger to eglGetDisplay(), see Test: DisplayVkOffscreen getting instantiated Change-Id: I584f9491b188f730f4ee9630173cc486ae7e8908 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/5729841 Reviewed-by: Roman Lavrov <romanl@google.com> Reviewed-by: Yuly Novikov <ynovikov@chromium.org> Commit-Queue: Roman Lavrov <romanl@google.com>
