feat: restore cursor column when cancelling goto mini mode

Browse source 
This commit refactors the numeric_input mini mode to make the input value
type generic. This allows the goto mini mode to store the origin column
along with the row. Also, this will allow more complex numeric_input modes,
for example a goto mini mode that supports column and row.
