all: implement wasmimport directive
Go programs can now use the //go:wasmimport module_name function_name
directive to import functions from the WebAssembly runtime.
For now, the directive is restricted to the runtime and syscall/js
packages.
* Derived from CL 350737
* Original work modified to work with changes to the IR conversion code.
* Modification of CL 350737 changes to fully exist in Unified IR path (emp)
* Original work modified to work with changes to the ABI configuration code.
* Fixes #38248
