decred: multiple nonces code cleanup

The double loop is not useful, and prefer the __thread attribute
to enhance the code readability (remove the 2D host arrays).

diff: show by default, rework shares diff storage
...
This will allow later more gpu candidates.
Note: This is an unfinished work, we keep the previous behavior for now
To finish this, all algos solutions should be migrated and submitted nonces attributes stored.
Its required to handle the different share diff per nonce and fix the possible solved count error (if 1/2 nonces is solved).

windows: add support for SM 2.1, drop SM 3.5 (x86)

Mostly to do compatibilty tests, SM 2.1 support is very limited
SM 3.0 code should run on SM 3.5 (only a few cards use this arch)
As i can't test SM 3.5, its best to let users do their own tests...

remains my original lyra2 implementation to fix... (cuda_lyra2.cu)
I guess some kind of memory overflow force the driver to allocate

Note: lyra2, lyra2v2 and script seems to have problems

Only stored in memory for now.. to display a table after the bench
ccminer -a auto --benchmark
