[GPU Service] Separate GPU Service out of SurfaceFlinger.
Historically GPU service lives in SurfaceFlinger because it's a convenient
hack. This patch separates GPU service out of SurfaceFlinger. The GPU service
is a service that accesses to GPU, queries GPU capabilities and reports back.
Minor: Replace Vector with std::vector.
BUG: 118347356
Test: Build, flash and boot, `adb shell cmd gpuservice vkjson` to verify
