Explicitly depend on //absl/strings:string_view where used.

Traditionally, `//absl/strings` provided string_view.h, but
it is its own target now and we should depend on it whenever
we include `absl/strings/string_view.h`, see comment here:

https://github.com/abseil/abseil-cpp/blob/a690167a55b9e210b7884d311759977c0f5669c9/absl/strings/BUILD.bazel#L94-L99

Apply this strict reading to absl itself.

In some cases, this also allowed to remove a dependency on the
bigger `//absl/strings` library.
