updated as part of Granite. Based on the original FPACOPS script
with modifications to remove actions that are not necessary for
an upgrade.

* cannon: Basic memory protections

Add memory protections against high memory allocations to the VM.
This prevents large allocations from causing the `heap` to overflow and
wrap into low memory, which could overwrite code and cause arbitrary code execution.

This reverts commit 59e02fb3ece7fc249223054944a0b1ff437aa64f.

This reverts commit 864e59a821e87f9dd00ae97f85add93fa3857597.

When the FDG is about to execute a step, we must add an additional
clock extension equal to the PreimageOracle challenge period. This
gives the PreimageOracle time to elapse.

* fix: no squeezing unfinalized proposals

Updates the PreimageOracle to correctly revert if a proposal has
not actually been finalized. This fixes a bug because the timestamp
is not set until after a proposal is finalized but all other
conditions in the squeeze function are met even before addLeaves
is called with the finalize boolean set.

A lot of instructions in the MIPS spec require that certain fields
be set to zero. Most of the time this isn't actually a problem but
this can cause side-effects in a few cases. A buggy compiler could
create an issue if it ever spit out non-compliant instructions.
This PR implements those zero value enforcement checks for all
instructions that we implement.

Existing step logic wrote the register offset into memory but the
compiler should already be doing this when the struct is defined.
Instead of writing directly into memory, this change verifies that
the memory at that location has the expected value which will
catch any cases where the compiler's memory allocation mechanism
changes in the future.

Modifies the MIPS contracts to enforce that state.exited is either
exactly zero or one and cannot have any other value.

Updates DelayedWETH to use call instead of transfer because
transfer only sends along 2300 gas which will cause the transfer
to fail if the owner contract uses lots of gas in the fallback
function. Adds tests that demonstrate that the function now works
appropriately under any reasonable amount of gas usage. In theory
this means the recovery function can be reentered but this isn't
an issue because the function is authenticated and is recovering
all of the ETH in the contract anyway.

Existing implementation of SRAV had a bug where it would perform a
shift with all bytes of the rs register when the spec says it
should only be using the lower 5 bits of the register. Updates the
implementation to reflect this, updates the existing test to use
the same test vector as provided in the open mips tests, and adds
fuzz tests that shows srav works as expected with rs values that
have more than the lower 5 bits set.

Updates MIPSInstructions so that it correctly reverts on calls to
add, addi, and sub that overflow/underflow. Additionally includes
tests that demonstrates that the unchecked versions of the same
opcodes allow for overflow/underflow.

Modifies the FDG constructor to correctly check that the
splitDepth +1 is gte the max game depth. Means that the splitDepth
is now limited to be 1 smaller than it was before. Fine in prod
but avoids a bug in the trace ancestor lookup logic.

FDGs with a split depth below 2 can trigger bugs in clock
extension. Since we don't expect to have a split depth anywhere
near 0 or 1 this is a low impact bug and doesn't have an impact
on production but should be prevented anyway.
