[Clang-Tidy] Create readability-math-missing-parentheses check

[PiotrZSL]

I'm adding this here so, i woudn't forget.
Create check that detect missing () around mathematical expressions when operators of different priority are used.

int main()
{
    return 2 + 2 * 2;
}

Should be:

int main()
{
    return 2 + (2 * 2);
}

Similar thing for other math operators.
Main purpose is to explicitly show evaluation order.
Consider adding option to skip constructions that properly handled from left to right like: 2 * 2 + 2.
