Unsupported statement: 'CompoundLiteralExpr'

[Happypig375]

Try to convert https://github.com/erincatto/box3d/blob/d421e45c828f6f853a145f726f0b9425d31146eb/include/box3d/math_functions.h using ClangSharpPInvokeGenerator and it will complain about Unsupported statement: 'CompoundLiteralExpr'. The workaround today is to rewrite them using the struct declaration and assignment pattern.

C# had no way to express these until very recently (C# 14/.NET 10) so there wasn't really a reasonable way to bind them.

I can look at adding support now, but may be a day or two.
