kmsan: silence -Wmissing-prototypes warnings
 
When building the kernel with W=1, the compiler reports numerous
warnings about the missing prototypes for KMSAN instrumentation hooks.

Because these functions are not supposed to be called explicitly by the
kernel code (calls to them are emitted by the compiler), they do not
have to be declared in the headers. Instead, we add forward declarations
right before the definitions to silence the warnings produced by
-Wmissing-prototypes.
