Daniel Holbert ae192ec3a5 Bug 1613192: Fix non-unified build bustage in layout/{base,generic} directories. r=TYLin
Summary of the changes/reasons:

- LayoutTelemetryTools.h directly uses several types whose headers it needs to
  include. (These includes were present in its .cpp file; I'm migrating them
  from there to the .h file, and I'm adding a new include for "Saturate.h" to
  provide the SaturateUint8 type.)

- LayoutTelemetryTools.cpp needs an include for MainThreadUtils.h, to provide
  NS_IsMainThread().

- StaticPresData.cpp needs an include for ServoUtils.h, to provide
  AssertIsMainThreadOrServoFontMetricsLocked().

- ZoomConstraintsClient.h needs a forward-decl for mozilla::dom::Document since
  it uses a pointer of that type in a function-decl.

- ScrollSnap.h needs forward-decls of nsPoint/nsRect for some references to
  those types in a method signature.

- nsGridContainerFrame.cpp needs an include for nsBoxLayoutState.h since it
  uses that type (it instantiates a nsBoxLayoutState instance).

- nsPlaceholderFrame.cpp needs a "using" decl for the mozilla::dom namespace in
  order to use the un-namespace-prefixed "Element" type.
