cmd/compile: allow more types for wasmimport/wasmexport parameters and results

Browse source 
As proposed on #66984, this CL allows more types to be used as
wasmimport/wasmexport function parameters and results.
Specifically, bool, string, and uintptr are now allowed, and also
pointer types that point to allowed element types. Allowed element
types includes sized integer and floating point types (including
small integer types like uint8 which are not directly allowed as
a parameter type), bool, array whose element type is allowed, and
struct whose fields are allowed element type and also include a
struct.HostLayout field.

For #66984.
