shader: introduce shader_active_uniforms()

The existing shader api only supports caller-provided uniforms
and attributes at instantiation time, with no ability to
introspect what uniforms are actually actively present in a given
shader.

This commit adds introspection of the active uniforms for a given
shader at creation time, as well as when reloaded, keeping the
information around to be accessed via shader_active_uniforms().

The immediate impetus for this is supporting runtime discovery of
uniforms present in the shader source, with the intention of
exposing these as sequencer tracks for external manipulation.
