This change allows to build with emscripten if offline (when passing the `--offline` parameter). Previously this failed because as part of locating emscripten we try to pull the latest repo version and install the desired emscripten version. With this change when `--offline` is specified we try to use the currently installed version of emsdk. If it isn't installed or if the wrong version is installed we will fail the build.

# So we try and locate emcc in common locations ourselves. The search pattern
|
|
# is:
|
|
#
|
|
# 1. Look for $EMSCRIPTEN_BASE (our primary emscripten variable), which should
|
|
# point to the folder that emcc is located in
|
|
# 2. Look for $EMCC which should point to the emcc executable
|
|
# 3. Look for emcc on the path
