Add a public build option for PDF.js

[Carlos Garcia Campos]

PDF.js increases the binary size of the library quite a bit, so embedders might want to disable it if they know they don't need PDF support at all.

- wihtout PDF.js: libwebkit2gtk-4.1.so.0.2.0 -> 91M
- with PDF.js: libwebkit2gtk-4.1.so.0.2.0 -> 95M

This is a developer release build in both cases.

I know we discussed this in bug #237513, but thinking about it more, webkit-pdfjs-viewer should never be treated as a unique origin on any port. Just move it outside the #if PLATFORM(GTK) || PLATFORM(WPE).

This isn't really specific to GTK/WPE right?

Well, the public build option is specific to GTK and WPE, for other ports it's an internal flag

I prefer not to change the behavior in this patch, this is just about adding a build option.
