contracts: Add automated weights for wasm instructions (#7361)

Browse Source 
* pallet_contracts: Inline benchmark helper that is only used once

* Move all max_* Schedule items into a new struct

* Limit the number of globals a module can declare

* The current limits are too high for wasmi to even execute

* Limit the amount of parameters any wasm function is allowed to have

* Limit the size the BrTable's immediate value

* Add instruction benchmarks

* Add new benchmarks to the schedule and make use of it

* Add Benchmark Results generated by the bench bot

* Add proc macro that implements `Debug` for `Schedule`

* Add missing imports necessary for no_std build

* Make the WeightDebug macro available for no_std

In this case a dummy implementation is derived in order to not
blow up the code size akin to the RuntimeDebug macro.

* Rework instr_memory_grow benchmark to use only the maximum amount of pages allowed

* Add maximum amount of memory when benching (seal_)call/instantiate

* cargo run --release --features runtime-benchmarks --manifest-path bin/node/cli/Cargo.toml -- benchmark --chain dev --steps 50 --repeat 20 --extrinsic * --execution=wasm --wasm-execution=compiled --heap-pages=4096 --output ./bin/node/runtime/src/weights --header ./HEADER --pallet pallet_contracts

* Added utility benchmark that allows pretty printing of the real schedule

* review: Add missing header to the proc-macro lib.rs

* review: Clarify why #[allow(dead_code)] attribute is there

* review: Fix pwasm-utils line

* review: Fixup rand usage

* review: Fix typo

* review: Imported -> Exported

* cargo run --release --features=runtime-benchmarks --manifest-path=bin/node/cli/Cargo.toml -- benchmark --chain=dev --steps=50 --repeat=20 --pallet=pallet_contracts --extrinsic=* --execution=wasm --wasm-execution=compiled --heap-pages=4096 --output=./frame/contracts/src/weights.rs --template=./.maintain/frame-weight-template.hbs

* contracts: Adapt to new weight structure

* contracts: Fixup runtime WeightInfo

* contracts: Remove unneeded fullpath of WeightInfo type

* Apply suggestions from code review

* Fix typo in schedule.rs

* Fix docs in schedule.rs

* Apply suggestions from code review

* Don't publish proc-macro crate until 3.0.0 is ready

* Optimize imports for less repetition

* Break overlong line
