• Updated EuiFlyoutResizable with new optional onResize callback (#7464)

Bug fixes

• Fixed an issue in EuiResizableContainer where onResizeEnd could become a stale closure when renders occured between resize start and end, resulting in an outdated version of a consumer's onResizeEnd callback being called (#7468)
• Fixed EuiTextArea to correctly fire onChange callbacks on clear button click (#7473)
• Fixed EuiContextMenu's panel titles & items to not show underlines on hover for non-interactive elements (#7474)

Deprecations

• Remove unused public EuiHue and EuiSaturation subcomponent exports. Use the parent EuiColorPicker component instead (#7460)
• Remove unused public EuiCommentTimeline subcomponent export. Use the parent EuiComment or EuiCommentList components instead. (#7467)
