Allow most third_party targets to use system libraries if asked.
This extends the pattern in freetype2 to expat, icu, libjpeg-turbo, libpng, libwebp, and zlib, and gives all these an arg to control which to use.
Homebrew doesn't have dng_sdk, piex, or sftnly, or I'd have done the same for them too.

+Third-party Dependencies
+------------------------
+
+Skia offers several features that make use of third-party libraries, like
+libpng, libwebp, or libjpeg-turbo to decode images, or ICU and sftnly to subset
+fonts. All these third-party dependencies are optional, and can be controlled
+by a GN argument that looks something like `skia_use_foo` for appropriate
+`foo`.
+
+Most of these third-party dependencies can also be satisfied by pre-built
+system libraries. If `skia_use_foo` is enabled, turn on `skia_use_system_foo`
+to build and link Skia against the headers and libaries found on the normal
+system paths. Remember, you can use `extra_cflags` and `extra_ldflags` to add
+include or library paths if needed.
+
+By default Skia will attempt to build and embed its own copies of these
+third-party libraries. This configuration is for development and testing only.
+We do not recommend shipping Skia this way. Note however, this is the only
+configuration of Skia that receives significant testing.
