Adds function names to host functions and improves logging listener (#697)

This improves the experimental logging listener to show parameter name
and values like so:

```
--> ._start.command_export()
        	--> .__wasm_call_ctors()
        		--> .__wasilibc_initialize_environ()
        			==> wasi_snapshot_preview1.environ_sizes_get(result.environc=1048572,result.environBufSize=1048568)
        			<== ESUCCESS
        		<-- ()
        		==> wasi_snapshot_preview1.fd_prestat_get(fd=3,result.prestat=1048568)
        		<== ESUCCESS
        		--> .dlmalloc(2)
        			--> .sbrk(0)
        			<-- (1114112)
        		<-- (1060080)
--snip--
```

The convention `==>` implies it was a host function call
(def.IsHostFunction). This also improves the lifecycle by creating
listeners during compile. Finally, this backfills param names for
assemblyscript and wasi.
