This PR implements the partial read functionalities in the freezer, optimizing
the state history reader by resolving less data from freezer.

This implements a backing store for chain history based on era1 files.
The new store is integrated with the freezer. Queries for blocks and receipts
below the current freezer tail are handled by the era store.

This pull request introduces a SyncKeyValue function to the
ethdb.KeyValueStore
interface, providing the ability to forcibly flush all previous writes
to disk.
This functionality is critical for go-ethereum, which internally uses
two independent
database engines: a key-value store (such as Pebble, LevelDB, or
memoryDB for
testing) and a flat-file–based freezer. To ensure write-order
consistency between
these engines, the key-value store must be explicitly synced before
writing to the
freezer and vice versa.

This PR improves error handling in the remotedb package by fixing two
issues:
1. In the `Has` method, we now properly propagate errors instead of
silently returning false. This makes the behavior more predictable and
helps clients better understand when there are connection issues.
2. In the `New` constructor, we add a nil check for the client parameter
to prevent potential panics. This follows Go best practices for
constructor functions.
These changes make the code more robust and follow Go's error handling
idioms without requiring any changes to other parts of the codebase.
Changes:
- Modified `Has` method to return errors instead of silently returning
false
- Added nil check in `New` constructor
- Fixed field name in constructor to match struct definition
This PR adds `DeleteRange` to `ethdb.KeyValueWriter`. While range
deletion using an iterator can be really slow, `DeleteRange` is natively
supported by pebble and apparently runs in O(1) time (typically 20-30ms
in my tests for removing hundreds of millions of keys and gigabytes of
data). For leveldb and memorydb an iterator based fallback is
implemented. Note that since the iterator method can be slow and a
database function should not unexpectedly block for a very long time,
the number of deleted keys is limited at 10000 which should ensure that
it does not block for more than a second. ErrTooManyKeys is returned if
the range has only been partially deleted. In this case the caller can
repeat the call until it finally succeeds.

This PR makes it possible to set custom headers, in particular for two scenarios:
- geth attach
- geth commands which can use --remotedb, e..g geth db inspect
The ability to use custom headers is typically useful for connecting to cloud-apis, e.g. providing an infura- or alchemy key, or for that matter access-keys for environments behind cloudflare.
