tint/sem: Record diagnostic severity modifications

Each sem::Node has a map which stores the diagnostic modifications
applied to that node. The sem::Info class provides a query to get the
diagnostic severity for a given AST node, by walking up the semantic
tree to find the tightest diagnostic severity modification. The
default severity is used if it was not overridden.

This allows components outside of the Resolver/Validator to determine
the diagnostic severity while walking the AST, which is required for
the uniformity analysis.
