Support auto-intra-tools-off in the key-value API

The --auto-intra-tools-off option was added in
https://aomedia-review.googlesource.com/c/aom/+/149021. However, it was
only added as an aomenc option and was not recognized by the key-value
API (the aom_codec_set_option() function). This CL corrects that.

Bug: aomedia:3281

(cherry picked from commit 4ab159e7565e0dc3c01722758bc3a4f9815d38c8)
