Change: [Emscripten] update to 2.0.34 and use Release over RelWithDebInfo (#9696)

Browse Source 
It turns out that having "-g" in the compile-statement causes
Emscripten to pick -g3, which makes for very big binaries. This
is very likely not your intention when building Emscripten, as
smaller really is better.

For comparison, with RelWithDebInfo the binary is ~80MB. With
Release it is ~7.4MB.
