Add fieldtrial config for V8 serialize options.

Add fieldtrial config for V8 serialize options.

V8 would like to gather real world performance data for two new serialization
options. It was recommended to:

    1. Pick one of two options for test, whichever you like better (more likely to advance).
    2. Make sure to change test config (fieldtrial_testing_config_*.json) if your belief changes.

I've picked "Serialize eager + pre-age code", since 1, this is the more
aggressive proposal and 2, it increases the code coverage. (This option
enables the code path for the other proposal + some additions.)

This adds the field trial for all platforms except iOS, since iOS Chromium
does not use V8.

Please edit your CL description to not mention Finch, since it's an internal

==========
Add fieldtrial config for V8 serialize options.

V8 would like to gather real world performance data for two new serialization
options via Finch. Advice from our Finch embassador was to add a field trial.
Specifically:

    1. Pick one of two options for test, whichever you like better (more likely
to advance).
    2. Make sure to change test config (fieldtrial_testing_config_*.json) if
your belief changes.

I've picked "Serialize eager + pre-age code", since 1, this is the more
aggressive proposal and 2, it increases the code coverage. (This option
enables the code path for the other proposal + some additions.)

This adds the field trial for all platforms except iOS, since iOS Chromium
does not use V8.

Done. (Sorry; should have known that.)
