Support optional message for dataclone error (#36308)

- [x] our [DataClone
error](https://github.com/servo/servo/blob/d733abfca02cdb9fd2af4f0d82ff050e25f71829/components/script/dom/bindings/error.rs#L80)
needs to support an optional message
- [x] we need to add support to our DOMException implementation to allow
an optional message to replace the default message
- [x] we need to create a new struct used by both StructuredDataReader
and StructuredDataWriter for storing the error message in the
report_error_callback
- [x] report_error_callback needs to cast the closure pointer to the new
struct
- [x] the code that [throws a DataClone
error](https://github.com/servo/servo/blob/5d1c64dba9cf3e65f770370eb17f00ad4114edce/components/script/dom/bindings/structuredclone.rs#L542)
needs to use the stored error message if it's available
