…tGap (#95) (#106)

fxLayoutGap emitted physical margin properties (margin-right/left) and
selected between them by reading the CDK Directionality (the `dir`
attribute). That broke layouts when the writing direction was set via CSS
`direction: rtl`, and required LTR/RTL branching throughout the directive.

Switch to logical properties, which the browser resolves against the
writing direction automatically:

  row          -> margin-inline-end
  row-reverse  -> margin-inline-start
  column       -> margin-block-end
  column-reverse -> margin-block-start
  grid margin  -> margin-inline / margin-block
  grid padding -> padding-inline / padding-block

This both fixes the RTL bug and removes now-dead direction handling: the
Directionality injection and its change trigger, the four direction-keyed
style caches and their selection in updateWithValue, and the
`directionality` field on LayoutGapParent.

Tests updated to assert the logical properties; full library suite passes
(478/478).

Closes #95
