handle logic to auto close and delete brackets

Handle Auto Close Parentheses, Braces, Brackets

To solved #488
I add logic to handle:

• Auto close: If you type '(' or '[' or '{' with have auto close that and cursor will go between these.
• Auto delete:
  For example: You have (|) ( this is parentheses with cursor between, if you delete - type BACK both open and close will be delele)

Could this feature be made optional?

For me this is one of the most annoying features in other editors, frequently causing me to write things like [2]] or if (some_thing) { do_something(); } )}). And with the auto-delete it makes it even harder to prevent because when I then delete the closing bracket it also deletes the opening one. Another example is retro-actively adding a () around an existing condition.

Some more general remarks:

• It leaks syntax of the language written into the editor itself.
• There are cases were you just want a single opening bracket, for example in multi line comments or strings.

@Consolatis You can try my ver first. Because delete only auto delete if between that is empty.
For example:

• [|] -> if your cursor is between and you type BACK button -> will auto delete both open and close
• [some thing]| -> if your cursor is right close and you type BACK button -> you just delete close one.

My auto just delete with not thing between open and close. Can you check that first. If still annoy for you I will add some change to make that to optional or remove that feature.

I'm not entirely sure about merging this logic just yet without having a settings model allowing users to turn this behavior off. I'll continue to let this PR sit for a while longer but try to keep it in the back of my mind.

@lhecker If needed, I’ll update with the settings ( from project) later. I see that my PR is currently out of date with the main branch.
