LTO in Rust produces multiple definition of `rust_eh_personality' (and
few others), and to overcome this --allow-multiple-definition has been
added.
Query for benchmark:
SELECT ignore(BLAKE3(materialize('Lorem ipsum dolor sit amet, consectetur adipiscing elit'))) FROM numbers(1000000000) FORMAT `Null`
upstream : Elapsed: 2.494 sec. Processed 31.13 million rows, 249.08 MB (12.48 million rows/s., 99.86 MB/s.)
upstream + rust lto: Elapsed: 13.56 sec. Processed 191.9 million rows, 1.5400 GB (14.15 million rows/s., 113.22 MB/s.)
llvm BLAKE3 : Elapsed: 3.053 sec. Processed 43.24 million rows, 345.88 MB (14.16 million rows/s., 113.28 MB/s.)
Note, I thought about simply replacing it with BLAKE3 from LLVM, but:
- this will not solve LTO issues for Rust (and in future more libraries
could be added)
- it makes integrating_rust_libraries.md useless (and there is even blog
post)
So instead I've decided to add this quirk (--allow-multiple-definition)
to fix builds.

Due to we need to substitude config for Rust builds (see #44762 for
details), the source dir is copied to the binary dir, but this is done
only once, so to detect changes in sources you need to run cmake,
without this patch.

Our crates has configuration files:
- config for cargo (see config.toml.in)
- and possibly config for build (build.rs.in)
Previously it uses source directory, and it will overrides files in the
source directory, which will require recompile of crates in case of
multiple builds for one source directory.
To avoid overlaps different builds for one source directory, crate will
be copied from source directory to the binary directory.

Before this patch corrosion requires that CMAKE_BUILD_TYPE matches the
CMAKE_CONFIGURATION_TYPES, which is
"RelWithDebInfo;Debug;Release;MinSizeRel", so that said, that if you
were using CMAKE_BUILD_TYPE=debug, it will not work.

Note, that it can the fail the client if the skim itself will fail,
however I haven't seen it panicd, so let's try.
P.S. about adding USE_SKIM into configure header instead of just compile
option for target, it is better, because it allows not to recompile lots
of C++ headers, since we have to add skim library as PUBLIC. But anyway
this will be resolved in a different way, but separatelly.

Right now it works for host platforms because of gcc package, that
includes gcc-cross sysroot.
Use bundled sysroot from contrib instead.
