rust: Upgrade 1.75.0->1.76.0

* Drop "--doc" option for rust oe-selftest since
it is not supported on bootstrap builds for
cross-targets.

* Drop the following backported patches which are merged
with rust v1.76 upgrade.

- custom-target-cfg.patch
- rustc-bootstrap.patch
- rv32-missing-syscalls.patch
- target-build-value.patch

https://blog.rust-lang.org/2024/02/08/Rust-1.76.0.html
* Drop 'rust-rustdoc' and 'rust-dbg' from 'exclude_packages' list
to check for rust reproducibility.
