Mitchell Hashimoto da27e6c908 libghostty: paste reads clipboard contents on demand, streams to pty ...

Follow up to #13978

`ghostty_terminal_paste` no longer takes the clipboard's data up front.
The request now carries only the list of available MIME types plus a
a callback that writes one representation's bytes into a `GhosttyWriter`. 

Previously an embedder had to load every representation for every MIME
type into memory before pasting. For a clipboard holding a large image
or video next to some text that could be hundreds of megabytes that
were never used.

I also took care to make sure that the data is only read once, to avoid
any time-of-check/time-of-use (TOCTOU) issues.

There is only one case where data might be fully buffered in memory now:
unsafe text data that needs to be checked. This is true for how Ghostty
GUI works today too.
