First baby steps to supporting memory accesses
...
Currently we don't actually sandbox the memory at all, so you can do evil things
like read and write the host's memory. We also don't support growing memory or
cranelift-compatible ABI that passes the memory offset as an argument.
We also always immediately allocate the buffer when encountering a memory section,
there is preliminary support for translating a buffer which can then have the real
offset replaced using relocations (and returning a different type when doing so)
but I haven't written the code that actually does relocation so it doesn't work yet.

Pass declare_signature's argument by value.
...
`parse_type_section` doesn't need the value after passing it, and this
allows callees to avoid cloning if they need their own copy.

Add functions to ModuleEnvironment to support reserving buffers up front.
...
These default to doing nothing, but implementations can override them to
preallocate buffers.
Also, reorder the functions in `ModuleEnvironment` to more closely
reflect the sequence from the WebAssembly module layout.
