File dialog requests can now specify the share and access mode they want out of the opened file. This means read-only access is now possible.
While doing this I noticed that the SDL3 backend had a memory leak *and* didn't match the behavior of the other backends. Cleaned up the code to avoid that.
In-engine commands that *can* specify read-only access on file open now do.
