This fixes the crashes occuring at startup with a non-empty shader cache. Because LinearDiskCache reads/writes to the storage of ShaderUid, ShaderUid must be trivially copyable. Additionally, adds a static assert to LinearDiskCache to ensure this doesn't happen in the future. The initialization of ShaderUid data has been moved to the code generation functions, so the above condition holds true.
