This allows cargo to use make's jobserver when building packages, by
marking the cargo command as recursive (with the + prefix[1]) and
setting MAKEFLAGS.
This also:
* Give cargo/x.py the build directory instead of having to change the
current directory (and opening subshells)
* Set PKG_BUILD_PARALLEL/HOST_BUILD_PARALLEL for Rust packages to enable
the use of make's jobserver

This consolidates all environment variables for cargo into:
* CARGO_HOST_CONFIG_VARS / CARGO_PKG_CONFIG_VARS
These contain all cargo-specific environment variables, i.e. without
"common" variables like CC.
* CARGO_HOST_VARS / CARGO_PKG_VARS (renamed from CARGO_VARS)
These contain all environment variables to be passed to cargo.
This also:
* Set the CARGO_BUILD_TARGET environment variable instead of using the
--target command-line option
* Update Python include files to use CARGO_HOST_CONFIG_VARS /
CARGO_PKG_CONFIG_VARS

This also:
* Modify the "release" profile in place of adding the "stripped" profile
Only the profile for target is modified; there are no file size
constraints for host.
* For host, build with the "release" profile
* For target, build with either the "dev" or "release" profile based on
CONFIG_DEBUG
There is no environment variable to specify the "strip" option, but
enabling this option is not necessary as the build system will already
strip binaries based on CONFIG_NO_STRIP / CONFIG_USE_STRIP /
CONFIG_USE_SSTRIP.

This allows rustc/cargo/etc to be called without having to set PATH, as
$(STAGING_DIR)/host/bin is already in PATH.
This also fixes CARGO_HOME not being set during Host/Configure and
Host/Compile.

In order to use $(RUSTC_TARGET_ARCH) in HOST_BUILD_DIR, the line to
include rust-values.mk in the Rust makefile was moved in
f489e019ac, causing it to be included
before package.mk is included.
This had the side effect of preventing "-lssp_nonshared" from being
added to RUSTC_LDFLAGS, because PKG_SSP is indirectly set by package.mk
(package.mk includes hardening.mk, hardening.mk sets PKG_SSP).
There is a deeper issue; it is the Rust package's PKG_SSP value that
causes RUSTC_LDFLAGS to be set and written to the Cargo config file. For
packages that use Rust to build, their PKG_SSP value does not affect the
linker flag.
This sets rustflags with the RUSTFLAGS environment variable, instead of
writing the value to the Cargo config file, allowing PKG_SSP from the
package being built to be used and for the package being built to modify
the rustflags used.
This also:
* Fix "-lssp_nonshared" being added to TARGET_CFLAGS instead of
RUSTC_LDFLAGS, when CONFIG_PKG_CC_STACKPROTECTOR_STRONG is set.
* Remove the use of $(RUSTC_TARGET_ARCH) in HOST_BUILD_DIR and move the
include line for rust-values.mk back to after package.mk.
Since the host build directory was moved under the target build
directory in efdbac38dc, it is no longer
necessary to separate build directories with RUSTC_TARGET_ARCH;
$(BUILD_DIR) already separates build directories by target.
* Add BUILDONLY:=1, as the Rust package does not build a target package.
* Install the Cargo config file as "config.toml" instead of "config", as
this is the preferred form[1].
* Rename RUST_CFLAGS to RUSTC_CFLAGS and CONFIG_HOST_SUFFIX to
RUSTC_HOST_SUFFIX, for consistency.
* Allow CARGO_VARS to be set before rust-values.mk is included.

This allows other packages access to RUST_ARCH_DEPENDS by including
rust-values.mk, instead of rust-package.mk which also sets
Build/Compile.

to pass environment variables for cargo process.
This is necessary when for example, cross-compiling
netavark.
