`emcc-default.rsp`:
- this replaces `emcc-flags.txt` which was generated at wasm build time
as the default set of flags.
`Emcc.props`:
- this replaces `emcc-version.txt` which was generated at wasm build
time, and contained the output of `emcc --version`, eg:
`emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 2.0.12 (d0e647bf266caad50943e78c9841e05e9c499a5d)`
- Instead of this, we now generate `Emcc.props`, which has:
`$(RuntimeEmccVersionRaw)` - full version string (`emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 2.0.12 (d0e647bf266caad50943e78c9841e05e9c499a5d)`)
`$(RuntimeEmccVersion)` - parsed version (`2.0.12`)
`$(RuntimeEmccVersionHash)` - parsed hash (`d0e647bf266caad50943e78c9841e05e9c499a5d`)
- these might be useful for nugets with native libraries for use with
wasm, for example
- The default options being used in the `Makefile` have been moved to
`wasm.proj`, and used to populate the new files
- this tries to retain the same flags as are being used currently, on
various platforms (eg. for windows the optimization flags differ)
- this is being done mainly to aid readability, and clarity
- a new target `WasmBuildNativeOnly` has been added, which should
(eventually) be usable before `publish`.
- this commit makes the changes for it, but it hasn't been tested in
it's final form

Doesn't WasmApp.Native.targets need to be added to the pkgproj?
Good catch! thanks, updated. |

I'm a little worried this was green before adding the files. We keep having problems like this. |
I agree. I was thinking of using the nugets with the wasm.build tests, to start with. It won't be a real workload based test though, since the sdk used is older, so probably wouldn't be prudent to depend on that for workload. |

We should strive to find problems as close to the source as practical, that doesn't mean catching everything but it does mean checking for patterns we've seen before. |

Can runtime packs include a props file that will be automatically loaded?

Should we move the base emscripten detection to the WorkloadManifest.targets where it will always be available (and knows how to require the workload when appropriate)?

should the value here be a property?
