Make sample data work with share-capable objects

[jportner]

As described in #100489, in the 8.0 release we are converting lots of saved object types to become "share-capable". One side effect of this is that newly created objects must have globally unique IDs (across all spaces).

It turns out that sample data object IDs are hardcoded, and these are created using bulkCreate. Which means that if you add sample data that contains share-capable objects in one space, then you try to add it in the second space, you'll run into a 409 unresolvable conflict error.

The home plugin needs to use the Import API instead of bulkCreate:

kibana/src/plugins/home/server/services/sample_data/routes/install.ts

Lines 157 to 160 in 574f659

	createResults = await client.bulkCreate(
	savedObjects.map(({ version, ...savedObject }) => savedObject),
	{ overwrite: true }
	);
