This fixes an issue where (elem func) was parsed as (elem funcref)
which meant we couldn't distinguish the two nodes in the AST. The fix is
to force the usage of index-based elements if func is used.

* Rename `canonical_abi_realloc` to `cabi_realloc`.

This follows the current Canonical ABI. This doesn't rename
`canonical_abi_free`, as that's expected to be removed when post-return
functions are implemented.

* Rename the "expected" type to "result".

This follows the current Canonical ABI.

* Implement function and value type name mangling.

This implements the name-mangling scheme in the current canonical ABI,
with the modification proposed in WebAssembly/component-model#104,
though that can be easily removed if the proposal is declined.

* Use name mangling in the bindings generators.

* Use the export base name rather than the mangled name for python identifiers.
