One Copyright Update to rule them all As many open source projects have started doing it, we're removing the current year from the copyright notice, so that we don't need to bump it every year. It seems like only the first year of publication is technically relevant for copyright notices, and even that seems to be something that many companies stopped listing altogether (in a version controlled codebase, the commits are a much better source of date of publication than a hardcoded copyright statement). We also now list Godot Engine contributors first as we're collectively the current maintainers of the project, and we clarify that the "exclusive" copyright of the co-founders covers the timespan before opensourcing (their further contributions are included as part of Godot Engine contributors). Also fixed "cf." Frenchism - it's meant as "refer to / see".

Implement shader caching * Shader compilation is now cached. Subsequent loads take less than a millisecond. * Improved game, editor and project manager startup time. * Editor uses .godot/shader_cache to store shaders. * Game uses user://shader_cache * Project manager uses $config_dir/shader_cache * Options to tweak shader caching in project settings. * Editor path configuration moved from EditorSettings to new class, EditorPaths, so it can be available early on (before shaders are compiled). * Reworked ShaderCompilerRD to ensure deterministic shader code creation (else shader may change and cache will be invalidated). * Added shader compression with SMOLV: https://github.com/aras-p/smol-v

Fix uninitialized variable ending up sent to Vulkan The first time a shader is compiled Godot performs the following: ```cpp for (uint32_t i = 0; i < SHADER_STAGE_MAX; i++) { if (spirv_data.push_constant_stages_mask.has_flag((ShaderStage)(1 << i))) { binary_data.push_constant_vk_stages_mask |= shader_stage_masks[i]; } } ``` However binary_data.push_constant_vk_stages_mask is never initialized to 0 and thus contains garbage data or'ed with the good data. This value is used by push constants (and many other things) thus it can be a big deal. Fortunately because the relevant flags are always guaranteed to be set (but not guaranteed to be unset), the damage is restricted to: 1. Performance (unnecessary flushing & over-excessive barriers) 2. Overwriting push descriptors already set (this would be serious, doesn't seem to be an issue) 3. Driver implementations going crazy when they see bits set they don't expect (unknown if this is an issue) This uninitialized value is later saved into the binary cache. Valgrind is able to detect this bug on the first run, but not on the subsequent ones because they data comes from a file. cache_file_version has been bumped to force rebuild of all cached shaders. Because the ones generated so far are compromised.

Implement Binary Shader Compilation * Added an extra stage before compiling shader, which is generating a binary blob. * On Vulkan, this allows caching the SPIRV reflection information, which is expensive to parse. * On other (future) RenderingDevices, it allows caching converted binary data, such as DXIL or MSL. This PR makes the shader cache include the reflection information, hence editor startup times are significantly improved. I tested this well and it appears to work, and I added a lot of consistency checks, but because it includes writing and reading binary information, rare bugs may pop up, so be aware. There was not much of a choice for storing the reflection information, given shaders can be a lot, take a lot of space and take time to parse.
