Emit { token in map with correct column meta

@josevalim the fix in 6a7511f is incomplete. Parser needs to be updated as well

Use %{} token meta in parser
Fixes #14740

[josevalim]

Can you please provide a test? Because I am not sure I see what needs to be fixed. For the %{} token, the beginning is column: 1 (i.e. where %{ starts). Structs are different because the % and { are separate. :) Thanks!

@josevalim if we only bump column on { token (e.g. from 1 to 2) then parser builds a %{} node taking that 2 as map column. See failed tests https://github.com/elixir-lang/elixir/actions/runs/17397565167/job/49382851600. The parser change in this PR makes it use column from %{} token and closing meta from {} pair.

The tests had passed locally for me. I guess the only explanation is that I forgot to save the file before running them. 🤦

Thank you, however, I will just review the previous PR, given the tokenizer is private API and that's simpler than doing the token dance here. :)
