Revert of Reland Auto-generate v8 version based on tags. (patchset #1 id:1 of https://codereview.chromium.org/843913009/)

Browse Source 
Reason for revert:
The gclient hook of v8 is not executed on this builder:

http://build.chromium.org/p/tryserver.chromium.linux/builders/android_aosp/builds/49765

Original issue's description:
> Reland Auto-generate v8 version based on tags.
>
> This relands the CL
> https://codereview.chromium.org/797503007/.
>
> It runs the version generation two times. First during
> runhooks as a fallback for recipes that loose git context
> (e.g. android_aosp). Second during compilation like in the
> original CL. In case of failures, the result from the
> runhooks call will be reused.

"""
Script to set v8's version file to the version given by the latest tag.
The script can be run in two modes:
1) As a gclient hook with the option --hook.
The script will write a temporary version file into the checkout.
2) During compilation as an action.
The script will write version.cc in the output folder based on the
tag info. In case of a failure it will fall back to the temporary file
from the hook call.
In most cases, 2) will succeed and the temporary information from 1) won't
be used. In case the checkout is copied somewhere and the git context is
lost (e.g. on the android_aosp builder), the temporary file from 1) is
required.
