[PATCH v6 0/1] define __builtin_add_overflow for MSVC

[Andre Muezerie <andremue@linux.microsoft.com>]

__builtin_add_overflow is gcc specific. A macro needs to be defined
for code using this to be compiled with MSVC.
Since only one driver is using this, this patch adds the macro to
that driver only. It can be moved to some common place if/when
needed.

v6:
- Moved definition of __builtin_add_overflow to the only driver that
  needs it, making it private to that driver.

v5:
- Combined patches 1 with 5 and 2 with 3.

v4:
- Added define in ice_osdep.h to use portable version of
  __builtin_add_overflow when using MSVC.
- Undid all changes from drivers/net/intel/ice/base/ice_nvm.c.

v3:
- Rebase on top of latest main.
