FastNoise GetValues() specialization (#7009)

Browse Source 
* Add comparison operator for use from unit tests.

Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com>

* First version of FastNoise benchmarks.

Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com>

* Simplified unit tests and added initial benchmarks.

Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com>

* Add GetValue vs GetValues unit test.

Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com>

* Moved Gradient test code into helper files for use from FastNoise.
Also added benchmarks for each type of FastNoise so that we can have some comparative values handy.
