Description

This PR replaces source-map with @jridgewell/gen-mapping and @jridgewell/trace-mapping.
This reduces package size.

before after diff (%)
package size 79.8kB 44.7kB -35.1kB -43.98%
unpacked size 311.0kB 155.9kB -155.1kB -49.87%

Simillar to #6746.

Additional context

Another approach is to turn source-map into dep. source-map is a dep of @vue/compiler-core/@vue/compiler-sfc.
Or source-map-js which is a dep of postcss (@vue/compiler-sfc).

source-map is still needed for type. (not included in bundle though)

Awesome! I think we can start with this change. Maybe instead of making source-map a dep, vue may end up also migrating to gen-mapping, trace-mapping?
