Rationale: https://github.com/maticnetwork/Polygon-Improvement-Proposals/blob/main/PIPs/PIP-36.md

This PR updated transfer to call during Plasma Deposits on MRC20 (ie matic token on Polygon PoS). The updates:

  • Fix pragma of token to 0.5.17 (all contracts are currently compiled to 0.5.17, this just removed the floating pragma specifically here)
  • MRC20.deposit: replace transfer with call, and bubble up any reverts, fixed gas of 5000 is passed.
  • MRC20.transfer is intentionally kept to re-use transfer, for external callers to support sending tokens to Gnosis Safe or SCW's, please use Access Lists.
  • Tests for the above.
