kcsan: Introduce __data_racy type qualifier

This commit adds a __data_racy type qualifier that enables kernel
developers to inform KCSAN that a given variable is a shared variable
without needing to mark each and every access.  This allows pre-KCSAN
code to be correctly (if approximately) instrumented withh very little
effort, and also provides people reading the code a clear indication that
the variable is in fact shared.  In addition, it permits incremental
transition to per-access KCSAN marking, so that (for example) a given
subsystem can be transitioned one variable at a time, while avoiding
large numbers of KCSAN warnings during this transition.
