8e7f398e50 Wasm: Remove code to adjust function indices based on imports 
With pre-linking we don't need this anymore. Pure Roc code can't add Imports.

a25101b378 Remove unusable variants from Align enum 
I discovered today that Wasmer throws an error if you use
"higher than natural" alignment in a store instruction.
So let's take them out of the enum.

a5c3809290 Delete DataCountSection. Not well-supported and only needed for instructions we don't use 
https://webassembly.github.io/spec/core/binary/modules.html#binary-datacountsec

Tools like wasm2wat and wasm-validate reject the module when this section is included!
Its purpose is to enable single-pass validation for two specific instructions that were
not in the original Wasm MVP: memory.init and data.drop.
We don't use them in our Roc backend. It seems to make sense just to drop the section.
