trie, core, eth: use db.has over db.get where possible

Fixes #24161

Fixes #24124

SyncProgress was modified in PR #23576 to add the fields reported for
snap sync. The PR also changed ethclient to use the SyncProgress struct
directly instead of wrapping it for hex-decoding. This broke the
SyncProgress method.

Fix it by putting back the custom wrapper. While here, also put back the
fast sync related fields because SyncProgress is stable API and thus
removing fields is not allowed.

Fixes #24176

Fixes #24167

New behaviour is that the endpoint returns results only for available
blocks without returning an error when it doesn't find a block. Note we
skip any block after a non-existent block.

This adds a header fetch for every block in range (even if header
is not needed). Alternatively, we could do the check in every field's
resolver method to avoid this overhead.

* core/vm: reverse bit order in bytes of code bitmap

This bit order is more natural for bit manipulation operations and we
can eliminate some small number of CPU instructions.
