Cleanup PER_VERTEX declarations for specialization

Cleanup PER_VERTEX declarations for specialization

This change harmonizes all of the PER_VERTEX declarations in the shader
specialization map so that they all use the same naming convention, and
have the same code formatting style. It also corrects some values that
were incorrect or missing for some tests.

Fixes:

KHR-GL44.geometry_shader.api.program_pipeline_vs_gs_capture
KHR-GL44.tessellation_shader.tessellation_control_to_tessellation_evaluation.gl_MaxPatchVertices_Position_PointSize
KHR-GL45.geometry_shader.api.program_pipeline_vs_gs_capture
KHR-GL45.tessellation_shader.tessellation_control_to_tessellation_evaluation.gl_MaxPatchVertices_Position_PointSize
