Revert of Disable user gesture checking for all autofill browser tests.

Revert of Disable user gesture checking for all autofill browser tests. (patchset #2 id:20001 of https://codereview.chromium.org/1125173006/)

Reason for revert:
This CL broke Linux GN Clobber bot.

Original issue's description:
> Disable user gesture checking for all autofill browser tests.
>
> When drmemory_full runs, the browser tests are slowed down enough to
> timeout the user gesture indicator, which prevents autofill from
> processing the input and passing the browser test. The fix is to disable
> user gesture checking for all autofill browser tests except
> AutofillRendererTest.IgnoreNonUserGestureTextFieldChanges.
