builtin read: enable bracketed paste

Browse Source 
We run __fish_enable_bracketed_paste on every shell prompt, and inside
edit_command_buffer. This protects from accidents when pasting control
characters, and makes sure the paste results in a single undo group.

Let's do the same for builtin read.

Found while doing the research for #10101
