Adds support for dumping the stack on Windows. Also enables in-process
stack dumping in d8 to dump the stack on exceptions and signals.

This CL changes the format of stack dumps from:
 1: V8_Fatal
 2: 0x1ac6ba5
 3: v8::internal::interpreter::BytecodeGenerator::Visit(v8::internal::AstNode*)
 4: v8::internal::interpreter::BytecodeGenerator::VisitForAccumulatorValue(v8::internal::Expression*)
 ...

  ./out/x64.debug/d8(v8::base::debug::StackTrace::StackTrace()+0x1e) [0x1c6ee5e]
  ./out/x64.debug/d8() [0x1c6ede5]
