When embedding SwitftShader into a third party application, the top
level cmake files may already include googletest and SPIRV-Tools. This
CL updates the SwiftShader tests to only try to pull in googletest if
the `gtest` target is not found and only pull in SPIRV-Tools if the
`SPIRV-Tools` target is not found.

D16_UNORM depth operations are performed in fixed point to avoid quirks
of ushort <-> float roundtrip

Some slight oddities to work around missing primitives:
- We only have CmpEQ, CmpGT. This matches SSE hardware reality.
  Everything else is made out of negations and operand swaps.
- We only have *signed* CmpGT. Make an unsigned CmpGT by biasing both
  16-bit operands by -0x8000.
- In non-quad-layout we don't have a good way to separate .xy and .zw
  halfs; reading via masked short4 reads, writing via individual
  component writes.

* ComputeProgram holds the codegen and the invoke logic. ComputeProgram::run() should probably be moved somewhere else (maybe Renderer?).
* ComputeProgram::run() is currently fully single threaded.
* The compute routines are currently not cached.

With that said, this is enough to start passing a whole bunch of dEQP compute tests.

the need for an intermediate representation by having the Blitter
use the vk::Image directly.
