feat(tvix/eval): implement unthunking in compiler r/6204
This feature allows the compiler to detect situations where the created thunk is useless and can be merged into the parent chunk instead. The only case where the compiler does this initially is when statically optimising a select expression. For example, previously the expression `builtins.length` compiled into two thunks: 1. An "inner" thunk which contained an `OpConstant` that had the optimised `length` builtin in it. 2. An "outer" thunk which contained an `OpConstant` to access the inner thunk, and the trailing OpForce of the top-level program. With this change, the inner thunk is skipped completely and the outer chunk directly contains the `length` builtin access. This can be applied in several situations, some easier than others, and we will add them in as we go along.
