Add MaxLengthAttribute support to ListControlWidget (#3469)

Browse Source 
ListControlWidget now respects the MaxLengthAttribute by disabling the add button when the collection reaches the specified maximum length. Also updated access rules to include MaxLengthAttribute.

Implements https://github.com/Facepunch/sbox-issues/issues/6361
