tint: Handle @diagnostic on block statements 

Use expect_compound_statement() in all the places that use
compound_statement in the WGSL grammar.

Handle attributes on statements inside Resolver::StatementScope, so
that the logic can be reused for the various places where block
statements are used. This will also make it easier to reuse this logic
when we allow these attributes on other types of statement in the
future.

Add an `EmitBlockHeader()` helper to the WGSL writer to reuse the
logic for emitting attributes on block statements for all the places
that use them.
