ui: Allow createPerfettoTable() to take a list of rows as records

[stevegolton]

Allow the as param in createPerfettoTable() to be an array of records in order to pre-populate the table with a type-safe list of types.

I.e.

as: string | readonly Record<string, SqlValue>[];

So we can use the function like this to initialise a table without having to hand craft the SQL.

await createPerfettoTable({
  engine,
  name: 'myTable',
  as: [
    {id: 1, ts: 100n, dur: 10, name: 'foo'},
    {id: 2, ts: 200n, dur: 50, name: 'bar'},
    {id: 3, ts: 300n, dur: 5, name: 'foo'},
  ],
});

This is simply a convenience feature to make it easier to create pre-filled tables, mainly for testing.
