Implement async shader compilation plus caching for GL ES 3

Browse source 
Async. compilation via ubershader is currently available in the scene and particles shaders only.

Bonus:
- Use `#if defined()` syntax for not true conditionals, so they don't unnecessarily take a bit in the version flagset.
- Remove unused `ENABLE_CLIP_ALPHA` from scene shader.
- Remove unused `PARTICLES_COPY` from the particles shader.
- Remove unused uniform related code.
- Shader language/compiler: use ordered hash maps for deterministic code generation (needed for caching).

If [code]true[/code], every time an asynchronous shader compilation or an asynchronous shader reconstruction from cache starts or finishes, a line will be logged telling how many of those are happening.
If the platform doesn't support parallel shader compile, but only the compile queue via a secondary GL context, what the message will tell is the number of shader compiles currently queued.

This is the maximum number of shaders that can be compiled (or reconstructed from cache) at the same time.
At runtime, while that count is reached, other shaders that can be asynchronously compiled will just use their fallback, without their setup being started until the count gets lower.
This is a way to balance the CPU work between running the game and compiling the shaders. The goal is to have as many asynchronous compiles in flight as possible without impacting the responsiveness of the game, which beyond some point would destroy the benefits of asynchronous compilation. In other words, you may be able to afford that the FPS lowers a bit, and that will already be better than the stalling that synchronous compilation could cause.
The default value is a conservative one, so you are advised to tweak it according to the hardware you are targeting.

<member name="rendering/gles3/shaders/shader_compilation_mode" type="int" setter="" getter="" default="0">
If set to [code]Asynchronous[/code] and available on the target device, asynchronous compilation of shaders is enabled (in contrast to [code]Asynchronous[/code]).
That means that when a shader is first used under some new rendering situation, the game won't stall while such shader is being compiled. Instead, a fallback will be used and the real shader will be compiled in the background. Once the actual shader is compiled, it will be used the next times it's used to draw a frame.
Depending on the async mode configured for a given material/shader, the fallback will be an "ubershader" (the default) or just skip rendering any item it is applied to.
An ubershader is a very complex shader, slow but suited to any rendering situation, that the engine generates internally so it can be used from the beginning while the traditional conditioned, optimized version of it is being compiled.
In order to save some loading time, you can use [code]Asynchronous + Cache[/code], which also causes the ubershaders to be cached into storage so they can be ready faster next time they are used (provided the platform provides support for it).
[b]Warning:[/b] Async. compilation is currently only supported for spatial and particle materials/shaders.

If asynchronous shader compilation is enabled, this controls whether [constant SpatialMaterial.ASYNC_MODE_HIDDEN] is obeyed.
For instance, you may want to enable this temporarily before taking a screenshot. This ensures everything is visible even if shaders with async mode [i]hidden[/i] are not ready yet.
Reflection probes use this internally to ensure they capture everything regardless the shaders are ready or not.
