Remove most of the blink::Task wrapping of WTF::Function outside WebTaskRunner

classes (see Issue 588224), this CL:
- Removes most of the blink::Task wrapping of WTF::Function.
- Removes most of #include "platform/Task.h".
- Replaces postTask(WebTaskRunner::Task*) with postTask(PassOwnPtr<Closure>) where possible.

Hi,

This is CL#1 of the 2 main CLs of my "Assign Thread Affinity to Task-related
classes" effort
https://docs.google.com/document/d/1iq4xaubtIL-LPArjgu33sVB_O1L47cQ96DLKXo5Qny8/.

This doesn't introduce behavior changes or assertion changes.

(CL#2 (WIP; https://codereview.chromium.org/1549143002/) will introduce
threading assertions to all WTF::bind()/WTF::Function.)

kinuko@, haraken@: PTAL.

skyostil@ alexclarke@, is this CL fine with your TaskRunner cleanup?

[kinuko, 2016-02-22 04:44:03]

lgtm as far as this lgt scheduler folks.

[haraken, 2016-02-22 09:39:26]

LGTM

[Sami, 2016-02-22 12:17:02]

lgtm.

[hiroshige, 2016-02-26 04:32:56]

alexclarke@, could you take a look?

[alex clarke (OOO till 29th), 2016-02-26 16:25:28]

Didn't realize you where waiting on me.  

LGTM
