Kbuild/Kconfig updates for 7.3

Kbuild updates
==============

  * Use --force-group-allocation when linking modules

    Have the linker resolve the COMDAT groups and place their members as
    regular sections instead of possibly leaving multiple copies in the
    resulting modules and unnecessary group metadata.

  * UAPI header files: Canonicalize __ASSEMBLER__ / __ASSEMBLY__ mixed
    use to __ASSEMBLER__

    There is an ongoing effort to change __ASSEMBLY__ to __ASSEMBLER__
    treewide.  For consistency, UAPI headers are normalised to use
    __ASSEMBLER__ only.  Normalisation is done in two subsequent patches
    to simplify a revert in the unexpected case of a regression report.

  * link-vmlinux.sh: Improve detection of third pass requirement

  * modpost: Canonicalize format of warnings and errors

  * Minor changes:
    - Remove srctree path from CHECK output
    - Set the initial value of subdir-rustflags-y
    - Remove broken and unused modules.builtin(.modinfo) targets from
      the top-level Makefile
    - Add symbol size for kallsyms symbols that can change size
    - modpost: Prevent leak when early return no suffix .o in
      read_symbols()
    - scripts/config: Update usage of POSIX sed
    - 'make tags': Add support for rust source files and prevent binary
      files from being analysed
    - Several spelling mistakes and rephrasing

Kconfig updates
===============

  * Add Julian Braha as Kconfig reviewer

  * Fix submenu rendering of negative dependencies

  * Minor changes:
    - merge_config.sh: Keep temp file in the output dir
    - Abort rather than loop for ever on EOF
