tint/resolver: Evaluate constant index accessors

If the object and index are both constant expressions, resolve the
index as a constant.

Note: Expectations have been updated for indexing on 'let's. Once
'const' is introduced, 'let' will no longer be treated as a constant
expression, and these expectations will be reverted.

Bug: tint:1580
