src: remove base64_select_table and base64_table

node::base64_encode() uses ::base64_encode() when the mode is Base64Mode::NORMAL, so base64_select_table is only ever called for Base64Mode::URL and thus only ever returns base64_table_url, but never base64_table. Also move base64_table_url into base64-inl.h. PR-URL: #44425 Reviewed-By: James M Snell <[email protected]> Reviewed-By: Minwoo Jung <[email protected]>
