app: improve gradient color-sampling speed

Browse Source 
Improve the speed of gimp_gradient_get_color_at(), which is used by
gimp:gradient during processing when the gradient cache is too big,
by disabling type checking, and inlining and avoiding some function
calls.

(cherry picked from commit 93f4b18704)
