[contracts] Port host functions to Weight V2 and storage deposit limit (#13565)

* added [unstable][seal2] call()

* updated test to cover new seal_call proof_limit

* docs updated

* add [seal2][unstable] instantiate() and test

* add [seal2][unstable] weight_to_fee() + docs and test

* add [seal2][unstable] gas_left() + docs and test

* update benchmarks

* add DefaultDepositLimit to pallet Config

* specify deposit limit for nested call

add test for nested call deposit limit

save: separate deposit limit for nested calls

* specify deposit limit for nested instantiate

save: works with test

cleaned up debugging outputs

* update benchmarks

* added missing fixtures

* fix benches

* pass explicit deposit limit to storage bench

* explicit deposit limit for another set_storage bench

* add more deposit limit for storage benches

* moving to simplified benchmarks

* moved to simplified benchmarks

* fix seal_weight_to_fee bench

* fix seal_instantiate benchmark

* doc typo fix

* default dl for benchmarking

more dl for tests

dl for tests to max

deposit_limit fix in instantiate bench

fix instantiate bench

fix instantiate benchmark

fix instantiate bench again

remove dbg

fix seal bench again

fixing it still

seal_instantiate zero deposit

less runs to check if deposit enough

try

try 2

try 3

try 4

* max_runtime_mem to Schedule limits

* add default deposit limit fallback check to test

* weight params renaming

* fmt

* Update frame/contracts/src/benchmarking/mod.rs
