swig: replace hand-written accessor wrappers with auto-generated #defines

SWIG generates accessor names as libnvme_STRUCT_MEMBER_get/set() but
libnvme exports them as libnvme_STRUCT_get/set_MEMBER().  Previously
nvme.i bridged this gap with ~35 hand-written C wrapper functions
(~130 lines of boilerplate) that had to be updated manually whenever
new accessors were added to the library.

Add generate-swig-accessors.py, a post-processing script that reads the
accessor header files produced by generate-accessors.py (accessors.h
and accessors-fabrics.h, covering both common and fabrics structs) and
emits nvme-swig-accessors.i containing one #define per accessor:

  #define libnvme_ctrl_name_get libnvme_ctrl_get_name

Parsing the .h files (not the .ld version scripts) ensures the output
is always in sync even before the .ld section labels are manually
bumped.  Object-like macros are used rather than function-like macros
since the call arguments follow naturally after macro expansion.

Add a new update-swig-accessors run_target in meson.build and extend
the update-accessors alias to include it.  Replace the hand-written
wrapper blocks in nvme.i with %include "nvme-swig-accessors.i".  The
four bridges that cannot be auto-generated (virtual member names or
!accessors:none annotations) are kept as #defines in a single block
next to the %include.
