Revert of mandoline: Fix ICU initialization. (patchset #31 id:570001 of https://codereview.chromium.org/1425853003/ )

Reason for revert:
Failures on Chromium Mojo Linux Perf which appears to be because the perf bots don't have an up to date kernel and on Chromium Mojo Android which has some weird crash.

Original issue's description:
> mandoline: Fix ICU initialization.
>
> We need to complete the initialization of ICU before we raise the
> sandbox. That means we can't pass a file descriptor to the ICU data file
> across mojo pipes. Due to how Android handles resources files, we also
> can't pass a file descriptor around inside the same process. So pass a
> raw pointer to a memory mapped file during the sandbox warm-up phase,
> and make a new option to initialize ICU from this raw pointer.
>
> But that just uncovers a bigger issue: we don't always call what was the
> sandbox warming code. If it's general initialization that needs to be
> called before we run MojoMain(), we need to include initialization code
> in most all main.cc implementations. This bakes a base initialize call
> into the mojo application library.
>
> This fixes a crash in the page cycler set, which happens when a page
> tries to do date operations, which fail because of missing locale data.
> This should let us raise the sandbox on the page cycler.
