Improve jsx-closing-bracket-location error message

[alopatin]

By adding expected column information for the closing bracket, as well
as reporting the error at the closing bracket instead of the opening
bracket. Parsing the error message should now be sufficient to allow
writing an external autofixer.

Example input test.jsx with default options:

<Provider
    store> // <--
    <App
        foo
    />
</Provider>

Resulting error:

test.jsx:2:10: Ereact/jsx-closing-bracket-location The closing bracket must be aligned with the opening tag (expected column 1 on the next line)

Note that the reported error location now corresponds to the closing > bracket on line 2, and that the error message now includes the exact location of where that closing bracket should have been.

Test Plan:
npm install
npm run test

Great! Thanks for this!

Parsing the error message should now be sufficient to allow writing an external autofixer.

Actually since ESLint now have an API to apply fixes we could directly add the autofixer in the rule. There is already an issue for this (#245) but I did not yet had the time to do it.
