Daniel Holbert d55c8c26d0 Bug 1590639 part 4: Fix non-unified build issues in layout/style. r=emilio
This patch:

- Gives layout/generic/AnonymousContentKey.h an include for `<stdint.h>` to
  provide the uint8_t type, and TypedEnumBits.h to provide the
  MOZ_MAKE_ENUM_CLASS_BITWISE_OPERATORS macro. (This is a change in another
  directory, but it's needed in order for layout/style/ServoStyleSet.cpp to
  build successfully.)
- Adds a missing "nsINode" forward-decl to dom/base/IdentifierMapEntry.h,
  because it uses that type in function declarations.  (This change is needed
  in order for layout/style/CachedInheritingStyles.cpp to build successfully.)
- Gives CSSStyleRule.cpp an include for PseudoStyleType.h,
  nsCSSPseudoElements.h, and CSSEnabledState.h because it uses those types.
- Gives GeckoBindings.cpp an include for gfxTextRun.h, to provide the definition
  of type gfxFontGroup (so GeckoBindings can call GetFirstValidFont() on an
  object of that type).
- Gives Loader.h an include for nsIContentInlines.h, to provide the inline
  function IsInUAWidget().
- Gives Rule.cpp an include for HoldDropJSObjects.h, to provide DropJSObjects().
- Gives nsImageLoader.cpp an include for DocumentInlines.h (and Document.h for
  good measure), to provide the inline function GetPresContext().
- Gives nsStyleStruct.cpp an include for DocumentInlines.h, to provide inline
  function Document::GetPresContext().
- Gives nsStyleTransformMatrix.h an include for Units.h (instead of gfxPoint.h,
  which isn't useful) to provide the CSSPoint type.
- Gives nsStyleTransformMatrix.h an include for ServoStyleConsts.h, to provide
  LengthPercentage and the various StyleRotate/StyleScale/StyleTransform/etc
  types. (These can't be easily forward-declared, because some of them are
  legitimate types whereas others are type aliases. We could theoretically
  forward-declare all of the underlying types and then repeat the type aliases,
  but that'd be verbose and unmaintainable.)
