Prior to this CL, a byte slice was allocated via make to use as the
absoluteSD argument passed to the Windows API MakeAbsoluteSD.

MakeAbsoluteSD then sets pointers outside the view of the GC, including
pointers within absoluteSD that point to other chunks of memory
we pass into MakeAbsoluteSD.

CL 653856 recently allowed more make results to be stack allocated,
which worsened the problems here and made it easier for those
pointers in absoluteSD to become dangling pointers, though the
core problems here existed before.

This CL instead allocates absoluteSD as a proper SECURITY_DESCRIPTOR
struct so that the GC can be aware of its pointers. We also verify the
pointers are as we expect, and then set them explicitly
in view of the GC.

We were slicing using a count of bytes, not a count of uint16s.

This CL adds RISC-V cryptography extensions detection.
Direct detection of the extensions zvkned, zvknhb, zvksed and
zvksh is not supported, since the crypto spec requires these
extensions implemented with data independent timing (zkt).

However, their presence may be inferred by checking for
the shorthand extensions: zvkn, zvknc, zvkng, zvks, zvksc, zvksg.
