Select: fix option wrap in multiple mode (#12329)

* Select: Fix (#11392 & #12327) Writing space become small when collapse-tags prop is added & input takes new line even if space is available when filterable & multiple props are true

* Changes as IE & Edge dosen't support display: contents

* Revert "Changes as IE & Edge dosen't support display: contents"

This reverts commit 21475c6daac3e0ca364b4a9889e899316e553839.

* Fixed issue - input going in new line even if there is space (collapse-tags)

* Made calculating with dynamic (replaced static 208 with el-select__tags dynamic width)

* Select: Fixed Bug - Extra Height

Fixed bug - getting extra height whenever last options width is most of same as select's width
