Initial driver for RSoV (RenderScript over Vulkan/SPIR-V)

Bug: 30964317

Supports the following:

* Allocations of 32-bit integers and floating point numbers and vectors
* Single-input single-output kernels
* Co-existence of RSoV scripts and CPU intrinsics

Added default .clang-format for driver code using Google C++ code style.

The RSoV driver is loaded, if and only if the property debug.rs.rsov is
set to non-zero.

Test: RSTest and CTS with debug.rs.rsov set to 0; and RSoVTest with
      debug.rs.rsov set to 1.
