[Build Speed] Reduce the cost of SerializedScriptValue.h and AXObjectCache.h

Slim WebCore headers to reduce build times
Reduce frontend parsing time by ~352s (2.5%) across a full debug build
by removing unnecessary includes from widely-used headers, replacing
heavy includes with forward declarations, and extracting inner structures
into separate headers.
Key changes:
- SerializedScriptValue.h: Extract Internals struct to a separate
private header (SerializedScriptValueInternals.h) behind a
unique_ptr. Reduces per-include cost from 578ms to 7ms (62 includers).
- AXObjectCache.h: Remove Document.h and RenderView.h includes by
moving inline functions out-of-line. Extract lightweight types to new
AXObjectTypes.h. Reduce inclusion count from 145 to 55 (saves ~166s).
- Remove unnecessary AXObjectCache.h from RemoteFrame.h,
RemoteFrameClient.h, and CompositeEditCommand.h, replacing with
lightweight AXObjectTypes.h or forward declarations.
- Remove redundant includes from Color.h, Node.h, Timer.h,
EventTarget.h, Document.h, Page.h, LocalFrameView.h, GraphicsContext.h,
SharedBuffer.h, and ~20 other widely-included headers.
- Use forward declarations for DestinationColorSpace, WritingMode,
PseudoElementType, UserGestureToken, SharedGamepadValue, and
ColorInterpolation where only pointers/references are needed.
- Add compensating includes to .cpp files that relied on transitive
includes through the slimmed headers.
CBA measurements (full debug build, arm64e):
Baseline: 14160.8s frontend parsing
Branch: 13808.8s frontend parsing
Saved: 352.0s (2.5%)
