Add cross-platform Workarounds to Context.
These are distinct from the renderer-level workarounds.
Add the first workaround, loseContextOnOutOfMemory. This is enabled
when the application enables reset notifications via KHR_robustness,
and is intended for more robust handling of errors in key APIs for
Chromium's correctness (in particular, sync objects).
Change Context::getResetStatus to persistently return the "lost" status
if it was set by calling Context::markContextLost. Previously, if
markContextLost was called but the implementation hadn't actually
received an error like a lost device, the "lost" reset status would be
dropped. Returning it only once to the caller is also fragile. Tested
this by manually injecting a failure in FenceSync11::clientWait and
ensuring that Chromium detected it as expected.
