Previously the builder scripts defined a readonly `VERSION` environment variable for the Keyman version. That caused problems when another (external) script tried to define a `VERSION` variable. We encountered this problem when trying to move the TC build steps of a configuration into a single script (#13399) when we tried to source `~/.nvm/nvm.sh`. This change uses a Keyman specific prefix for the version variables and renames `VERSION` → `KEYMAN_VERSION` etc. Unfortunately these variables are used in a lot of places, so this turned out to be a bit of a yak shave.

|

# 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
