Fixes an autoscroll bug that sometimes obscures the current row behind a sticky header. The bug was caused by `Editor::autoscroll_vertically` using the `sticky_header_line_count` value that was cached during the previous render, which isn't necessarily the number of sticky headers that the scroll target needs, e.g. - when jumping to a definition - when pressing the up arrow key when the selection is in the topmost visible row with `"vertical_scroll_margin": 0` This fixes that by not caching `sticky_header_line_count` and instead querying Tree-sitter on the fly to get the number of sticky headers that the scroll target needs. Performance-wise this seem okay, I measured it to take less than 200µs on my machine using a very large Rust file (and there are still some possible ways to optimize this if necessary). In particular, the pathological huge single-line file case as discussed in #48450 shouldn't be an issue here because unlike the main sticky header Tree-sitter query, here we query the outline items that contain a particular point rather than those that intersect an entire row. The `ScrollCursorTop` handler is also simplified to use the same shared function for counting the number of sticky headers, since that action doesn't rely on autoscroll.
