Manuel Rego Casasnovas 6354070dee Bug 1445615 [wpt PR 10027] - [css-grid] Add support for calc() in gutter properties, a=testonly
Automatic update from web-platform-tests[css-grid] Add support for calc() in gutter properties

There was a crash in debug if you use calc()
mixing fixed and percentage values due to the wrong DCHECK
in GapLength constructor. The patch fixes this assert.

In addition LayoutGrid::GridGap() was also wrong and didn't consider
calc() either. The fix is again easy just using the proper check.

Regarding testing, the parsing tests have been updated to include
this combination of fixed and percentage values in calc().
At the same time, the patch actually uses "grid-" prefixed properties
in the tests that were supposed to test those.
Last, two new tests are added to verify the proper behavior of calc()
with mixed values on a grid layout container.
