Add pixel canvas feature flag to all desktop platforms.

We're eventually going to launch pixel canvas on Windows and Linux, so
the flag should be available on those platforms for testing. It will now
should up in about:flags.

a couple of issues when Pixel Canvas is enabled. Windows 10 v1709, Chrome Beta 67.0.3396.18 (64-bit), Windows 10 system scaling is 175%.

Issue #1: on the New Tab page, if you do not have the bookmarks bar turned on, there is a black line between the top chrome and the new tab page bookmarks bar (see attached screenshot)

 Issue #2 : when you hover your cursor over an item in the downloads bar, the text changes, it seems to stretch? see this video https://drive.google.com/file/d/17r7IPEqNUCPoX0gNawBSfEpsJB-DKFrU/view?usp=sharing

Sorry just noticed another: in Incognito windows, there is a white line underneath the bookmarks bar on the New Tab page

Just noticed another issue: when the window is maximized, the "Minimize" icon is blurry.

Here's one issue that's present both with and without pixel canvas, but is more noticeable with pixel canvas enabled: the tab separators peek out from behind the active tab.  There's substantial flickering as the window is resized, too.

I enabled this flag out of curiosity, but it seems to be even blurrier than when disabled. I'm using 150% display scaling on Windows 10. Have I misunderstood what this function aims to achieve?
here's another issue enabling Pixel Canvas causes: sometimes, the bottom of the user icon gets chopped off, but when you hover your cursor over it, it's no longer chopped off. My system scaling is 175%. To repro this, try clicking the menu button beside it, that seems to get it to misbehave
