Workbench: Support Odd Number Of AA Samples

Workbench render engine did not work when an odd number of AA samples
were used. A user could enter these values by disabling AA or set the
number of AA samples in the Render/Film panel to an odd number.

This commit will not perform TAA passes when AA is disabled.
For supporting the setting of 5 or 11 samples the bitmask was replaced
by an if statement as this was making the odd number not render
correctly.

As extra introduce the jitter samples of 5 and 11 so the images will
be more clean. a jitter sample of 11 used to read outside the allocated
space of the jitter samples.
