Remove old checks from pipeline.c and verify that they're handled in validation

Remove old checks from pipeline.c and verify that they're handled in validation

Most checks were already handled in DrawState.
Added additional check for invalid patchControlPoints along with a new test, but test can't run on sample driver b/c TESS shaders not supported by the shader compiler.

For check that VBO vtx & attrib binding counts don't exceed VB array limit, added comment noting that this is a device-specific limit that should be captured in API-defined "maxVertexInputBindings" and added to DeviceLimits.

Also added pending task for ParamChecker to fix how it handles arrays in vkCreateGraphicsPipelines() call. It has a bug in how it handles check that each shader "stage" is within acceptable enum limits.
