Stop using Number.prototype.toLocaleString() for numeric console form…

…at specifiers

https://bugs.webkit.org/show_bug.cgi?id=259146

Reviewed by Patrick Angle.

`console.log("%i", 1000)` should have the same output as `console.log("1000")`.

* Source/WebInspectorUI/UserInterface/Views/ConsoleMessageView.js:
(WI.ConsoleMessageView.prototype._formatWithSubstitutionString.floatFormatter):
(WI.ConsoleMessageView.prototype._formatWithSubstitutionString.integerFormatter):
Remove calling `Number.prototype.toLocaleString` as that can insert unwanted text (e.g. commas).
