Add namespaces to duplicated Skia code.

When pdfium is imported into Google's internal repository, the recently
copied Skia decimal formatting code causes only-defined-once violations
because many Google internal projects depends on Skia through Google's
own copy. This patch puts pdfium's private copy of the needed function
into a namespace.
