Revert of Enable noexcept on Windows, use for a few move constructors. (patchset #3 id:40001 of https://codereview.chromium.org/2771643002/ )

Reason for revert:
Seems to have broken Windows build with args.gn as:

> is_debug = true
> is_component_build = true
> enable_nacl = false
> is_chrome_branded = true
> symbol_level = 2
> target_cpu = "x86"
> is_win_fastlink = true
> is_clang = false
> win_console_app = true
> win_linker_timing = true

Original issue's description:
> Enable noexcept on Windows, use for a few move constructors.
>
> MSVC complains if you use noexcept with no exception handling mode specified (as we do).
> This code disables the warning. noexcept on move constructors allows better optimizations
> in some cases.
> http://en.cppreference.com/w/cpp/language/noexcept_spec
>
> Updates a few common classes' move constructors to use this.
