Timeline: check category presence in list, not string equality

Timeline: check category presence in list, not string equality

... when testing for trace event category.
Trace event categories are comma-separated list and individual
itmes may come and go, so it's never correct to compare string
category list for equality against a single category. Split them
on comma and check category presence instead.

Source/devtools/front_end/sdk/TracingModel.js:612: return
this._parsedCategories.indexOf(categoryName) >= 0;
I'd expect it to be a Set.
