To round off #2444 we need to codegen exception throwing in a few places

PlatformNotSupportedException for lazy (not Direct PInvoke) DllImport's
EntryPointNotFoundException When an attempt is made to WasmImport different functions using the same WasmImport module and function name, no import is produced.

Then uncomment the tests for these in HelloWasm.cs.

A few more items:

After making the PIs lazy by default, remove -sERROR_ON_UNDEFINED_SYMBOLS=0 from our emcc options.
Likewise with --unresolved-symbols=ignore-all with WASI.
