Checksum address output in log_address event and broadcast files

[ckoopmann]

Component

Forge

Describe the feature you would like

Current Behaviour

Addresses emitted in log events as well as broadcast json-files are not checksumed.
This leads to compiler errors when copy pasting this address back into a script etc.

While there is a workaround using forge fmt this is suboptimal since it introduces another unnecessary command / step and also negates the original purpose of checksums protecting against accidental modification of the value.

Proposed Behaviour

Emit only checksummed addresses both in log events as well as broadcast json-files.

Additional context

Can be seen as an extension of: #2674
