feat(Table): Added column resizing

[bentleyvk]

Closes #84

• In order to resize columns, we need to know their widths and make every column static width therefore I am saving widths inside column.resizeWidth that I got from ref.
• When one column width is increasing another one is decreasing in the same amount. If next column has disabled resize then it is looking for the next one that is resizable.
• It is favoring minWidth and maxWidth therefore you can't resize past those.
• Because columns widths are static, I need to handle table resize too. For this I am temporally making columns kind of dynamic width again by setting flex-grow and flex-shrink, then getting new widths and making columns static again.
• useResizeColumns hook is taken from react-table and I make it work with ownerDocument also cleaned up code a bit and made it to resize sibling columns.

So are you going to undo it? 😄

[bentleyvk]

Too much work, I'll just leave it here and hope nobody sees it 😁

[mayank99]

at least add initial. It is considered outdated UX practice for tooltip to follow cursor.

Do you have a link for this guideline?

[mayank99]

Check our standards.

The guideline was updated in BWC standards first:

The tooltip should be anchored to the item that is being hovered and should not follow the cursor as it moves.

And then refined in iTwinUI standards:

It is anchored to the hovered item and fades out when the cursor moves away from the item.

Removed for now.
