FlatTableHeader does not allow for content wrapping

[johnb-sage]

Description

I'm using FlatTable and have some long header text that causes overflow at small viewports widths, such as 320px. Currently FlatTableHeader has white-space: nowrap so is not responsive.

Suggested solution

Ideally all components are responsive by default and we opt out of the native behaviour explicitly, so my preference is to remove the 'white-space: nowrap'.
