  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
