Sync rust-toolset macros to rust-packaging v25.2

Browse Source 
This bring RHEL rust-toolset in sync with the latest Fedora
rust-packaging, most importantly:

* Fedora's new style (-v vendor) vendoring is implemented. The old RHEL
style (-V #) vendoring is still supported, at least until we can convert
everything in ELN.

* Automatic generation of bundled provides using %cargo_vendor_manifest.
However, instead of depending on cargo2rpm, a very stripped-down version
of just its parse-vendor-manifest command is provided as a private
script, along with a fileattr to call it.

Other changes incorporated in this commit:

* -Cstrip=none added to %build_rustflags.

* --profile rpm is used instead of --release.

* Errors in spawned commands are now caught.

* Comments and whitespace are synced for easier comparison with Fedora.

* --target all is dropped from license and vendor macros, to avoid false
  alarms from windows crates.
