issue: https://github.com/flutter/flutter/issues/166101 


**step 1:** Add struct SemanticsFlags in semantics_node.h and class
SemanticsFlags in dart:ui, it's still a bitmask in embedder and
framework.

* Embedder 
add a struct FlutterSemanticsFlags
add FlutterSemanticsFlags* to FlutterSemanticsNode2

* web engine
 use the new class

* SemanticsUpdateBuilder.updateNode
pass a list of bools instead of bitmask

* Framework
use the SemanticsFlags class instead of bitmask

* flutter_tester
use the SemanticsFlags class instead of bitmask
