This is now just `extra_build_script_input_roots`.

[gnrt] Use `..._input_roots` for everything and remove `..._src_roots`.
This change avoids the following problems:
* Having to say `extra_input_roots = ['../data']` **and also**
`extra_src_roots = ['../data']` in `gnrt_config.toml` entries for
multiple ICU crates. The repetition was introduced because
`..._input_roots` ignores `.rs` files. But in both cases the
discovered files are exposed as GN `inputs` (not `sources`).
This was reported a while ago by @manishearth in chat, but I forgot to
open a bug and follow-up... :-(
* General confusion about how things work, which was encountered when
tweaking import of `zerocopy` for fuzzing. This was reported recently
and captured in https://crbug.com/508339800.
Before this change `extra_input_roots` wouldn't cover `.rs` files, so
the removal of `extra_src_roots` means that `extra_input_roots` has to
also cover `.rs` files after this change. This in turn means that we
need to explicitly list files one-by-one in
`build/rust/std/gnrt_config.toml` to avoid adding unnecessary `.rs`
files to the generated `BUILD.gn`. This is a bit unfortunate -
hopefully this will be fixed by adopting `glob` or a similar globbing
crate in a follow-up CL.
Tested by manually running the following tools (and including the
results in this CL):
* `tools/crates/run_gnrt.py gen`
* `tools/rust/gnrt_stdlib.py`
* `cargo test` and `cargo clippy` in `tools/rust/gnrt`
