* perf: pre-compute instance init functions

When we construct a row, we iterate over the table's features and
initialise any which have an `initRowInstanceData`.

This is expensive since most don't have such a method.

We actually know when we construct the table which features have this
method. This changes the table construction to store the initialisers up
front so when we create a row, we can just iterate the already known
initialisers.

* fix(table-core): bind initialiser to feature

* cache init functions consistently for all table objects

…accessor keys (#6444)

fix(table-core): preserve undefined in DeepValue for optional deep keys

When a deep string accessor key traverses an optional (or nullable)
parent key, `DeepValue` dropped the `undefined` from the resolved value
type. This made `getValue()` for a path like `user.salary.amount` typed
as `number` even when `salary` is optional, hiding a possible `undefined`
that the runtime accessor (which uses optional chaining) can return.

Distribute over the leaf union and map `null`/`undefined` members to
`undefined`, matching the optional-chaining semantics of the deep
accessor function.
release: v9.0.0-beta.56

…r pass (#6452)

The FlexRender components computed `result` in a plain getter that the
template reads twice (component-branch check, then content), re-invoking the
user's cell/header/footer render function on every read. Cache the getter so
the render function runs exactly once per render pass.
