Brad King d361bf365e Emscripten: Drop hard-coded -sMAIN_MODULE and -sSIDE_MODULE flags

These flags are only needed for builds involving shared libraries,
and can cause undesirable behavior when they are not needed.
They also have variants with values like `=2`.  For now, just require
projects to add the flags when needed so they have full control.
In the future we may be able to add an abstraction to control them,
and automatically enable them when linking to shared libraries
or creating them.

Fixes: #27232
Issue: #27240
