This fixes flutter/flutter#141001 This also fixes flutter/flutter#143743 * We need to always call `setStrutEnabled(true)` on `StrutStyle`. * `getLineMetricsAt` had reversed ternary logic. * Ported unit tests from CanvasKit over to UI to cover Skwasm and HTML * The HTML renderer should return 0 line metrics for an empty paragraph.

Suggested change
| if (ui.ParagraphBuilder.shouldDisableRoundingHack) { | |
| paragraphStyleSetApplyRoundingHack(handle, false); | |
| } | |
| paragraphStyleSetApplyRoundingHack( | |
| handle, | |
| !ui.ParagraphBuilder.shouldDisableRoundingHack, | |
| ); |
