Rust fixes for v6.11 (2nd)

Toolchain and infrastructure:

 - Fix builds for nightly compiler users now that 'new_uninit' was split
   into new features by using an alternative approach for the code that
   used what is now called the 'box_uninit_write' feature.

 - Allow the 'stable_features' lint to preempt upcoming warnings about
   them, since soon there will be unstable features that will become
   stable in nightly compilers.

 - Export bss symbols too.

'kernel' crate:

 - 'block' module: fix wrong usage of lockdep API.

'macros' crate:

 - Provide correct provenance when constructing 'THIS_MODULE'.

Documentation:

 - Remove unintended indentation (blockquotes) in generated output.

 - Fix a couple typos.

MAINTAINERS:

 - Remove Wedson as Rust maintainer.

 - Update Andreas' email.
