Simplify checks for dav1d_get_uleb128 out overflow

leb128 is duplicated in a few other places, like the input modules for the CLI. Could you also look at them and see if they can be simplified as well?

James: I am not familiar with dav1d. I just searched for "leb128" and "<= 3 " and "== 4 " in the source tree. I found the leb128() and leb() functions in tools/input/parse.h that have the same logic and can be simplified as well.

Do you know of any other copy of leb128 in dav1d?

No, seems those are the only other copies. Thanks for looking.

James: I couldn't figure out how to create a merge request from my local dav1d tree, so I created a separate merge request for tools/input/parse.h using the Web UI: !1031 (merged)

Sorry about the inconvenience.
