### vm: fix V8 compilation cache support for vm.Script
Previously repeated compilation of the same source code using `vm.Script`
stopped hitting the V8 compilation cache after v16.x when support for
`importModuleDynamically` was added to `vm.Script`, resulting in a performance
regression that blocked users (in particular Jest users) from upgrading from
v16.x.
The recent fixes landed in v21.1.0 allow the compilation cache to be hit again
for `vm.Script` when `--experimental-vm-modules` is not used even in the
presence of the `importModuleDynamically` option, so that users affected by the
performance regression can now upgrade. Ongoing work is also being done to
enable compilation cache support for `vm.CompileFunction`.
