Joyee Cheung c2d79208d6 vm: reject in importModuleDynamically without --experimental-vm-modules
Users cannot access any API that can be used to return a module or
module namespace in this callback without --experimental-vm-modules
anyway, so this would eventually lead to a rejection. This patch
rejects in this case with our own error message and use a constant
host-defined option for the rejection, so that scripts with the
same source can still be compiled using the compilation cache
if no `import()` is actually called in the script.
