Rename ShaderType enum to ShaderVisibility
Renames ShaderType in GrGLShaderBuilder to ShaderVisibility. It is now
used solely as a bitfield. Methods that previously accepted a single
ShaderType value are split into separate calls:
- getShader -> vsGetShader, gsGetShader, fsGetShader
- emiitFunction -> fsEmitFunction
- appendTextureLookup -> fsAppendTextureLookup
No change in functionality. This is a refactoring to allow us to
separate the vertex/geometry and fragment parts of GrGLShaderBuilder.
