Move FuzzedDataProvider to //base and expose to blink

This patch moves FuzzedDataProvider from //net/base to //base. We also
expose a wrapper type in blink platform for use in Blink fuzzers.

This patch also implements a very simple fuzzer for TextResourceDecoder,
which stress tests code operating on a raw byte stream.

BUG=638653
