Implement `gn edit "shard"` subcommand

Adds the `shard` subcommand to `gn edit` to split a target into
fine-grained shard targets based on source file stems.

Each shard inherits the original target's compiler flags, defines,
visibility, and conditionals, while stripping existing dependencies.
The original target is converted to a group (or specified group type)
depending on the newly created shards.

Supports optional arguments to customize the sharded target and group types:
  gn edit "shard [sharded_target_type] [group_type]" <labels...>
