Chengzhong Wu b11ee4cad3 lib: allow skipping source maps in node_modules 
Files in `node_modules` are not authored by the user directly and the
original sources are less relevant to the user.

Skipping source maps in `node_modules` improves the general
performance. Add `module.setSourceMapsSupport(enabled, options)` to
skip source maps in `node_modules` if it is needed. This moves
all source maps related API to `node:module` and this a step to
promote the source maps API to stable.

legendecas 803a7b2b23 src,lib: print source map error source on demand 
The source context is not prepended to the value of the `stack` property
when the source map is not enabled. Rather than prepending the error
source context to the value of the `stack` property unconditionally,
this patch aligns the behavior and only prints the source context when
the error is not handled by userland (e.g. fatal errors).

Also, this patch fixes that when source-map support is enabled, the
error source context is not pointing to where the error was thrown.
