Shaders: Improve types.

[s-rigaud]

Description

I am trying to improve the types for Shader passes. I try to make a single type that can be used and reference everywhere but I found some inconsistencies:

• some passes are missing a name property
• LuminosityHighPassShader is using an old shaderID property (outdated I think)
• ConvolutionShader is defining a buildKernel function that might just be passed as an utils like other shaders

some passes are missing a name property

Ideally, each shader object has a name. That also improves shader debugging.

LuminosityHighPassShader is using an old shaderID property (outdated I think)

Yes, I think it's safe to remove the property in this PR.

ConvolutionShader is defining a buildKernel function that might just be passed as an utils like other shaders

I think we should move buildKernel() into BloomPass as a module scope function.
