near-sdk-sim 3.2.0: Expose cur block and fix storage costs (#390)

* Expose `cur_block` and `genesis_config` from `RuntimeStandalone`. This allows to manipulate block time, e.g. set to a given timestamp.
* Use `RuntimeConfig::from_protocol_version` that fixes storage costs issue. Fixes: #388 
* Set root account balance to one billion tokens.

## Test plan:
- Modify FT test to verify storage cost fix by limiting initial deposit to 5 NEAR. It is not enough with old storage cost (50kb) and enough with new storage cost (500kb)

* make block time configurable to sim contract tests that depend on env::block_time

* Update near-sdk-sim/src/runtime.rs

* use block_prod_time name to make it matches nearcore

* Expose cur_block. Fix storage cost

* Fix initial supply

* Modify FT test to verify storage cost fix

* Rework RuntimeConfig from genesis
