Kernel: Add the ability to verify we don't kmalloc under spinlock.
Ideally we would never allocate under a spinlock, as it has many
performance and potentially functionality (deadlock) pitfalls.
We violate that rule in many places today, but we need a tool to track
them all down and fix them. This change introduces a new macro option
named `KMALLOC_VERIFY_NO_SPINLOCK_HELD` which can catch these
situations at runtime via an assert.
