weETH OFT adapter contract upgrade

[seongyun-ko]

@jtfirek :)

We are upgrading our OFT {token and adapter} contracts to have these features:

• OFT bridge pausing: Introduces a role PAUSER_ROLE that can be shared with hypernative to pause bridging to and from the native chain. This pauser role only halts bridging operations
• Pairwise rate limiting: The current iteration of our OFT contracts only rate limits outbound transfers on our token contract. This upgrade extends the layerzero RateLimter contract to allow for the rate limiting of inbound transfers as well. Also integrates rate limiting into our UpgradeableOFTAdapter contract
• Deprecate default admin: We have 2 roles {owner, default} that can set critical parameters so I consolidated all of this under owner. I also created this documentation on all the roles here

New OFT contract: etherfi-protocol/weETH-cross-chain#14
