forc-debug: Add ABI support for decoding log values

[JoshuaBatty]

Description

Adds support for ABI files in forc-debug to decode log values while debugging using the CLI. Users can now:

for example:

tx tx.json abi.json 

When the Sway ABI Registry is available, the debugger will automatically fetch ABIs for deployed contracts. Have an issue open to implement this here #6862

Updates documentation to show decoded log output, adds tab completion for ABI files, and refreshes bytecode examples to match current output.

The test_cli test has been updated to take an ABI and check that the correct decoded value is returned.
