[PATCH v4 00/11] rust: generate_rust_analyzer.py: define host crates and scripts

[Tamir Duberstein <tamird@gmail.com>]

This series updates rust-project.json to differentiate between host and
target crates, where the former are used as dependencies of the `macros`
crate. Please see individual commit messages for details.

The first 3 commits contain mechanical formatting changes and are
optional. The series can be taken without them.

I avoided more significant formatting or changes where possible to
reduce the diff. Unfortunately `scripts/generate_rust_analyzer.py` is
not consistently formatted before nor after this series.

The 5th commit ("scripts: generate_rust_analyzer.py: use
str(pathlib.Path)") can also be considered optional. It removes an
inconsistency I noticed while working on this series and which occurs on
a line which churns in this series anyway.

The last 3 commits can also be considered optional, as they can be
submitted separately. I included them in this series because they depend
on it, but they can be split out if this is preferred.
