combine common implementation of LC helpers (#4542)
* combine common implementation of LC helpers

Combine replicated helper code from Altair/Capella/EIP4844 into single
`Forky` based implementation. Also convert `template` to `func` to avoid
selection of incorrect overload.

* fix

use `ForkedLightClientStore` internally (#4512)
When running `nimbus_light_client`, we persist the latest header from
`LightClientStore.finalized_header` in a database across restarts.
Because the data format is derived from the latest `LightClientStore`,
this could lead to data being persisted in pre-release formats.

To enable us to test later `LightClientStore` versions on devnets,
transition to a `ForkedLightClientStore` internally that is only
migrated to newer forks on-demand (instead of starting at latest).

LC data fork cleanup (#4506)
Distinguish between those code locations that need to be updated on each
light client data format change, and those others that should generally
be fine, as long as a valid light client object is processed.

The former are tagged with static assert for `LightClientDataFork.high`.

The latter are changed to `lcDataFork > LightClientDataFork.None` to
indicate that they depend only on presence of any valid object.
Also bundled a few minor cleanups and fixes.

Also add `Forky` type for `LightClientStore` and minor fixes / cleanups.

add `LightClientHeader` wrapper (#4481)
The light client data structures were changed to accommodate additional
fields in future forks (e.g., to also hold execution data).

There is a minor change to the JSON serialization, where the `header`
properties are now nested inside a `LightClientHeader`.
The SSZ serialization remains compatible.

make LC data fork aware (#4493)
In a future fork, light client data will be extended with execution info
to support more use cases. To anticipate such an upgrade, introduce
`Forky` and `Forked` types, and ready the database schema.
Because the mapping of sync committee periods to fork versions is not
necessarily unique (fork schedule not in sync with period boundaries),
an additional column is added to `period` -> `LightClientUpdate` table.
