feat(dapp-connector): Add CIP-30 signData support

[michaeljscript]

Description / Change(s) / Related issue(s)

Implements CIP-30 signData using @emurgo/msl-mobile-bridge.

After some consideration I've decided to use @emurgo/msl-mobile-bridge instead of Dullahan (https://github.com/Emurgo/dullahan) implementation, for the following reasons

• Dullahan is not yet published on npm and hereby would require us to copy the implementation into yoroi and later maintain the implementation
• Copy of Dullahan implementation would require us to install and manage new dependencies, such as @noble/hashes or @noble/curves
• It would not be only a copy and the solution would require many changes to fit our needs
• Usage of @emurgo/msl-mobile-bridge seems more straightforward (similar to what on extension is used with @emurgo/cardano-message-signing-browser)

The below mentioned iOS issue in https://github.com/Emurgo/msl-mobile-bridge is already resolved.

May need https://github.com/Emurgo/msl-mobile-bridge/pull/1 to be merged before this PR is ready to fix iOS build issues.
