The Buildroot manual was already providing some details on how to
integrate Cargo packages, and those details now need to be updated
with a proper documentation for the cargo-package infrastructure, as
well as updates related to vendoring support, which affects how
dependencies are handled.
In addition, now that we have vendoring support for Cargo packages,
let's rewrite the dependency management section in a more accurate
way.
We drop the part about the local cache of the registry, because
+CARGO_HOME+ in Buildroot points to $(HOST_DIR)/share/cargo, which is
not shared between builds nor preserved accross builds, so its effect
as a cache is limited.

There is no debug profile on cargo. The available profiles are: dev
(enabled by default), release, test and bench.

As Cargo is either installed by host-rust or host-rust-bin, the
Cargo-based packages should depend on host-rustc.

Back in commit 025b863e6f, the option
BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS was introduced, to
separate the option that host packages needing Rust should depend on
(BR2_PACKAGE_HOST_RUSTC_ARCH_SUPPORTS) from the option that target
packages needing Rust should depend on
(BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS).
Since the example in the manual is showing a target package, we must
use BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS.

utils/check-package complains as follows:
package/rustc/rustc.mk:10: possible typo: RUST_TARGET_NAME -> *RUSTC*
package/rustc/rustc.mk:18: possible typo: RUST_HOST_NAME -> *RUSTC*
As RUST_{HOST,TARGET}_NAME are related to the Rust compiler, it
sounds sensible to rename them to RUSTC_{HOST,TARGET}_NAME.
So update all rust related packages to use the new variables.
