Move microtask queueing logic from JavaScript to C++

This avoids the appearence of a leak due to storing a JSObject
as the microtask_state in the strong root list, and allows callers
to call Isolate::RunMicrotasks() without having any v8::Context
available (as at least Blink has interest in doing).

The queue is now a strong root, represented as a FixedArray of JSFunctions
(or empty_fixed_array, if it's empty); it doubles in size when it needs to grow.
The number of elements in the queue is stored in Isolate::pending_microtask_count().

Decouple CpuFeatures from serializer state.

Traditionally, we cross compile a snapshot iff the serializer is enabled.
This will change in the future.

Changes:
 - CpuFeatures probing is done once per process, depending on whether we
   cross compile.
 - CpuFeatures are consolidated into the platform-independent assembler.h
   as much as possible.
 - FLAG_enable_<feature> will only be checked at probing time (already the
   case for ARM).
 - The serializer state is cached by the MacroAssembler.
 - PlatformFeatureScope is no longer necessary.
 - CPUFeature enum values no longer map to CPUID bit fields.

  - It is now possible to print the stack pointer. There is only one
    remaining restriction: The `csp` register cannot be printed unless
    it is the current stack pointer. This is because it is modified by
