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.

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.

Re-index all internal functions to make room for imported external functions
...
Linked external functions must be declared in the Import section,
and they must come first in the function index space.
In other words, internal function numbers start at the number of imports.
However we don't know in advance how many builtins the code may call,
and we don't want to add more passes over the full IR. Instead we re-index
function references at the end of code generation.

Add linker data for strings, and deduplicate them
...
For references to addresses of constant strings, we make an entry in
reloc.CODE and configure the relocation type to say it points at a
memory address. (At least I think this is right, I can't test it yet!)
The same info can also be used for de-duplication.
It turns out we don't need reloc.DATA. I had misunderstood it.
The use case for that would be constant nested data structures,
where constant data would contain pointers to other constant data.
I don't think we're doing this in Roc at all, but not sure.
