Migrate from assertThat(foo).named("foo") to assertWithMessage("foo").that(foo).

(The exact change is slightly different in some cases, like when using custom subjects or check(), but it's always a migration from named(...) to [assert]WithMessage(...).)

named(...) is being removed.

This CL may slightly modify the failure messages produced, but all the old information will still be present.

Tested:
    TAP --sample for global presubmit queue
