feat(kibana-data-discovery, obs-exploration-team): replace title props and wrap EuiButtonIcon with EuiToolTip

[weronikaolejniczak]

Relates to elastic/eui#9566

Important

These changes should be carefully tested visually by each code owner. Wrapping with EuiToolTip instead of passing title leads to another DOM node and can potentially break the layout. In such cases, I would appreciate committing appropriate fixes to this PR directly, I cannot possibly setup and run all Kibana functionalities to fix every regression.

This PR:

• wraps ALL EuiButtonIcon with EuiToolTip, the content is the same as aria-label, any title passed to EuiButtonIcon is removed,
• changes several title cases (not truncation related) to use EuiToolTip instead (if applicable).

Pinging @elastic/eui-team (EUI)

Code looks good and overall the change from EUI side is correct.

However I found some quirks which are probably on @elastic/obs-exploration-team side, I'd appreciate if they also take a look as co-owners.

The tooltip for summary column looks unnecessarily wide, which on smaller screens causes it to scroll. Firstly I thought there's no closing icon at all, but it was overflowed and obscured:

It also doesn't adjust if you resize window while having popover open.

After changes in this PR it causes even more quirky UI effects - even if you open popover on a bigger screen, the tooltip position looks way off:

I didn't dive very deep here, so I might be mistaken, but it seems like obs team is adding a fixed width here for the wrapper, which is not a very good practice and seems to be a root cause for the issue:

kibana/src/platform/packages/shared/kbn-discover-contextual-components/src/data_types/logs/components/summary_column/summary_column.tsx

Line 189 in c272470

<EuiFlexGroup direction="column" css={{ position: 'relative', width: 580 }}>

That being said, I'll leave the final approval to @elastic/obs-exploration-team
