Manual overloads for ImGui functions accepting text (#2319)
* wip2 * Implement AutoUtf8Buffer * reformat * Work on manual bindings * restructure * Name scripts properly * Update utility functions to use ImU8String * add overloads * Add more overloads * Use ImGuiWindow from gen, support AddCallback * Use LibraryImport for custom ImGuiNative functinos * Make manual overloads for string-returning functinos * Make all overloads with self as its first parameter extension methods * Fix overload resolution by removing unnecessary * in => scoped in * Fix compilation errors
