Add a new abstraction called span store in bor consensus. This makes the header verification stateless as instead of fetching validator set (of a span) from genesis contract, we rely on span from heimdall itself for validator set. This doesn't change any assumptions for consensus as the data in genesis contracts is written by fetching span details from heimdall in the first place.
This helps us with multiple things such as header verification for snap sync, validating producer set against header's extra data, and using heimdall as a source of truth instead of making a contract call to genesis contract which generally leads to issues when importing side chains (as we need to use the side chain state and not canonical).
Span store is a minimal cache which maintains last 10 spans in memory. It provide simple read methods via span id and block number so that we can use it in consensus.
This PR removes open telemetry based tracing from the whole mining workflow. The tracing extended into consensus and core blockchain functions from miner is also removed in this PR. We weren't checking the tracing from a long time and the way it was implemented increased the code complexity a lot.
Block execution contains the time it takes to fetch state sync data from heimdall, which sometimes returns data with long latency (> 1s). When the latency is significant, the chain execution time will be affected and become inaccurate. This PR isolate the time of heimdall requests from block execution.
Tests that are crucial to for verifying the verkle testnet functions properly.

rebased https://github.com/ethereum/go-ethereum/pull/29766 . The
downstream branch appears to have been deleted and I don't have perms to
push to that fork.
`TerminalTotalDifficultyPassed` is removed. `TerminalTotalDifficulty`
must now be non-nil, and it is expected that networks are already
merged: we can only import PoW/Clique chains, not produce blocks on
them.

This PR moves the logging/tracing-facilities out of `*state.StateDB`,
in to a wrapping struct which implements `vm.StateDB` instead.
In most places, it is a pretty straight-forward change:
- First, hoisting the invocations from state objects up to the statedb.
- Then making the mutation-methods simply return the previous value, so
that the external logging layer could log everything.
Some internal code uses the direct object-accessors to mutate the state,
particularly in testing and in setting up state overrides, which means
that these changes are unobservable for the hooked layer. Thus, configuring
the overrides are not necessarily part of the API we want to publish.
The trickiest part about the layering is that when the selfdestructs are
finally deleted during `Finalise`, there's the possibility that someone
sent some ether to it, which is burnt at that point, and thus needs to
be logged. The hooked layer reaches into the inner layer to figure out
these events.
In package `vm`, the conversion from `state.StateDB + hooks` into a
hooked `vm.StateDB` is performed where needed.

Way back we've added `common.math.BigMin` and `common.math.BigMax`.
These were kind of cute helpers, but unfortunate ones, because package
all over out codebase added dependencies to this package just to avoid
having to write out 3 lines of code.
Because of this, we've also started having package name clashes with the
stdlib `math`, which got solves even more badly by moving some helpers
over ***from*** the stdlib into our custom lib (e.g. MaxUint64). The
latter ones were nuked out in a previous PR and this PR nukes out BigMin
and BigMax, inlining them at all call sites.
As we're transitioning to uint256, if need be, we can add a min and max
to that.
Clique currently depends on the `accounts` package. This was a bit of a
big cannon even in the past, just to pass a signer "account" to the
Clique block producer. Either way, nowadays Geth does not support clique
mining any more, so by removing that bit of functionality from our code,
we can also break this dependency.
Clique should ideally be further torn out, but this at least gets us one
step closer to cleanups.
