fix(extmarks): disallow removing extmarks in on_lines callbacks

decor_redraw_start (which runs before decor_providers_invoke_lines) gets
references for the extmarks on a specific line. If these extmarks are
deleted in on_lines callbacks then this results in a heap-use-after-free
error.

Fixes #22801
