Detect problematic blob size at link time

[xermicus]

Emit a compiler warning (or error) if we detect the final blob size to exceed the pallets limits.

Tasks

• Add a command line flag to provide the memory limit (different chains can exhibit different limits), and assume AH as default
• Helper to calculate the maximum linked blob size given the static memory buffer and the the pallet limits
• Check it after linting and emit a warning if over the threshold
• By default it should error out but we want to have a flag to ignore it
