[EuiBasicTable] Implement nameTooltip API in columns prop

[acstll]

Summary

This PR implements the feature request from #7963

It adds a nameTooltip prop for columns in the EuiBasicTable, in order to easily render a tooltip in a column header.

Regarding the actual API, I left a comment in the original issue with a question; and a comment in the source.

Before

name: (
  <EuiToolTip content="Their mascot is the Octokitty">
    <>
      Github{' '}
      <EuiIcon
        size="s"
        color="subdued"
        type="questionInCircle"
        className="eui-alignTop"
      />
    </>
  </EuiToolTip>
),

After

name: 'GibHub',
nameTooltip: {
  content: 'Their mascot is the Octokitty',
},

@mgadewoll I refactored this back to the originally intended API: nameTooltip in EuiBasicTable.columns and tooltipProps in EuiTableHeaderCell — hopefully this is ready now, thanks for the patience 🙂
