pulled out of #117213 where this change was already approved

This only affects rustdoc, and has up to 20% perf regressions in rustdoc. These are unavoidable, as we are simply doing more checks now, but it's part of the longer term plan of making rustdoc more resistant to ICEs by only accepting valid Rust code.

Looks like unavoidable regressions for a correctness fix, and can be marked triaged.

For the relnotes: the effort to prevent broken code to be accepted by rustdoc will continue, closing the gap between rustc and rustdoc.

these changes should have future incompat lints instead of going directly to breaking code

The crater queue is long, so someone else here can kill the run if they think this is excessive.

rust: Upgrade to version 1.75.0.
083dfbe 
Pkgsrc changes:
 * Adjust patches and cargo checksums to new versions.
 * For an external LLVM, set dependency of llvm >= 16, in accordance
   with the upstream changes.
 * Mark that on NetBSD we now need >= 9.0, so 8.x is no longer supported.
 * On NetBSD/sparc64 10.x, we now need GCC 12 to build the embedded
   LLVM, which is version 17; apparently GCC 10.4 or 10.5 mis-compiles it,
   resulting in an illegal instruction fault during the build.
   Ref. rust-lang/rust#117231
