Bug Fix (#882) Use correct feature flags with srtool (#884)

# Goal
The goal of this PR is to make sure that the correct feature flags are
being used with srtool for wasm generation

Closes #882 

# Discussion
- srtool default-features flag does not work as intended
- Instead using build-opts
- Enabled debug logging in srtool for easier checking
- Added subwasm check to test the output wasm
