refactor(tvix/eval): statically resolve select from constant attrs r/5831
When resolving a select expression (`attrs.name` or `attrs.name or
default`), if the set compiles to a constant attribute set (as is most
notably the case with `builtins`) we can backtrack and replace that
attribute set directly with the compiled value.

For something like `builtins.length`, this will directly emit an
`OpConstant` that leaves the `length` builtin on the stack.
