fix(createError): preserve original error stack

[danielroe]

Currently errors logged by h3 always point to h3 itself rather than the source of the error, e.g.:

[h3] [unhandled] H3Error: window is not defined
    at createError (file:///private/tmp/vueqr/node_modules/.pnpm/h3@0.7.14/node_modules/h3/dist/index.mjs:238:15)
    at Server.nodeHandler (file:///private/tmp/vueqr/node_modules/.pnpm/h3@0.7.14/node_modules/h3/dist/index.mjs:431:21) {
  statusCode: 500,
  fatal: false,
  unhandled: true,
  statusMessage: 'Internal Server Error'
}
[nuxt] [request error] window is not defined
  at createError (./node_modules/.pnpm/h3@0.7.14/node_modules/h3/dist/index.mjs:238:15)  
  at Server.nodeHandler (./node_modules/.pnpm/h3@0.7.14/node_modules/h3/dist/index.mjs:431:21)

This PR changes it to the original stack trace:

[h3] [unhandled] ReferenceError: window is not defined
    at $id_aX1WMBYGcH (file:///private/tmp/vueqr/.nuxt/dist/server/server.mjs:4520:5)
    at async __instantiateModule__ (file:///private/tmp/vueqr/.nuxt/dist/server/server.mjs:8426:3) {
  statusCode: 500,
  fatal: false,
  unhandled: true,
  statusMessage: 'Internal Server Error'
}
[nuxt] [request error] window is not defined
  at $id_aX1WMBYGcH (./.nuxt/dist/server/server.mjs:4520:5)  
  at async __instantiateModule__ (./.nuxt/dist/server/server.mjs:8426:3)

Would you please provide a (nitro) reproduction how do you throw errors? I think we might use a simpler method but need to try.

Update:

• I tried with v8 native Error.captureStacktrace with no luck (might try again later)
• Added implementation to use a lazy getter for input.stack also try catch to avoid runtime errors. V8 at least, generates stack trace string when this property is being accessed which is why doing this to delay and only access when needed by runtime
