[issue42864] Improve error messages regarding unclosed parentheses

[Pablo Galindo Salgado]

New submission from Pablo Galindo Salgado :

Consider this file:

```
x = (


```

The error that we get is:

❯ python ../a.py
  File "/home/pablogsal/github/python/master/../a.py", line 6

^
SyntaxError: unexpected EOF while parsin

This is quite uninformative of the actual problem, which is the closed 
parentheses.

The same happens with something like this:

( 1+2

  File "/home/pablogsal/github/python/master/lel.py", line 3

^
SyntaxError: unexpected EOF while parsing

With some effort, we can include the location of the unclosed parentheses.
