JoostK 6e5f076330 perf(ivy): share instances of DomElementSchemaRegistry (#34332)
To create a binding parser, an instance of `ElementSchemaRegistry` is
required. Prior to this change, each time a new binding parser was
created a new instance of `DomElementSchemaRegistry` would be
instantiated. This is an expensive operation that takes roughly 1ms per
instantiation, so it is key that multiple allocations are avoided.

By sharing a single `DomElementSchemaRegistry`, we avoid two such
allocations, i.e. save ~2ms, per component template.
