This was dropped in
bdc2be1e01
but it's needed for EPEL 10, so adding it back.

(cherry picked from commit 175d35473cf8885da93bc888f7f4a54a369c84cd)
The upgrade path was broken because the Rust version compares less than
the rust2rpm-based package version that was in RHEL 8 and 9. With a new
name and appropriate Obsoletes and Provides, it should upgrade cleanly.

We also need to use the corresponding compiler-rt version and
use the llvm-profdata from the correct path.
The compat build is now enabled by defining llvm_compat_version.
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.
rust-srpm-macros is a dependency of redhat-rpm-config so that Rust-based
SRPMs can rely on these particular macros. In RHEL 9 and earlier,
rust-srpm-macros was a separate source package which was included in
RHEL. Since then, it became a subpackage of rust-packaging in Fedora.
In order to not pull in any part of rust-packaging into RHEL 10, thereby
allowing it to be maintained separately in EPEL, those macros are
provided here instead.
