No-Op draws when no active VS and/or FS is present
According to the OpenGL ES 3.1 spec:
7.3. PROGRAM OBJECTS
If there is no active program for the vertex or fragment shader
stages, the results of vertex and fragment shader execution will
respectively be undefined. However, this is not an error.
To handle this, if no VS or FS is present in the active Program/PPO,
we will no-op the draw command.

Vulkan: Support VS, FS, and CS in the same PPO
This CL adds support for a Program Pipeline Object to have a VS, FS,
and CS attached to the same PPO and then using that PPO for both draw
and dispatch calls.

Vulkan: Move cached samplers/images and has*() to ProgramExecutable
The active samplers and images are being moved from Program into
ProgramExecutable to unify interacting with them for Programs and
ProgramPipelines
Also, create some helper functions for gl::Program that ProgramExecutable can
call to make it easier for ProgramPipeline to respond to similar
queries for each of the Programs in the ProgramPipeline.

Create the ProgramExecutable Class
The ProgramExecutable class is being created to collect data structures
that are common to both Programs and ProgramPipelines, as well as any
shared functions. This allows callers to request the current
ProgramExecutable from the State and make
Program-/ProgramPipeline-specific queries without needing to know
exactly which responded. This will also allow the necessary data
structures to only be populated and stored within the ProgramExecutable
when necessary and reused as often as necessary.
