expression: remove useless HandleOverflowOnSelection

[lcwangchao]

What problem does this PR solve?

Issue Number: close #50278

Problem Summary:

The function HandleOverflowOnSelection seems useless. It was introduced in PR #14081 to solve some bugs.

However, in PR #16014, when converting a string to bool, we use StrToFloat instead of StrToInt. StrToFloat does not raise overflow error and all other errors should be swallowed in StrToFloat when the statement is select ...

We can remove HandleOverflowOnSelection safely now.

What changed and how does it work?
