add sampling countermeasures to the kernel
...
this evolves the TRNG state further after reporting any raw samples
for QC to make it harder to reason about the TRNG state after QC.

add RawTrng SysCall to Xous API
...
This SysCall is introduced because not all hardware targets can
afford the luxury of a private TRNG port for the kernel.
In this case, an API is needed to exfiltrate random numbers from
the kernel so we can inspect them and check them for health.
If a TRNG is operating correctly, cherry-picking some values
out of it to QC the operation of the TRNG should be harmless.
Of course, nothing is truly stateless, and there is always a chance
that someone could construct a gadget using this to reduce the
potential state-space of the final random number generator. Therefore,
this API is (a) gated behind a feature flag and (b) any implementation
that plans to expose this should be coded with some countermeasures
to reduce data leakage after sampling.

endpoint enumeration now working

turns out that you *have* to enable the endpoints after your
address has been assigned. You can't do it before.
