Bypass signal() to avoid validation and cli related overhead

[DavisVaughan]

Another ~30% faster by avoiding .rlang_cli_format_fallback() and getting to specify cli(use_cli_format = FALSE) explicitly

cross::bench_branches(\() {
  library(lifecycle)
  
  # trigger the 8 hour warning once
  deprecate_soft("1.1.0", I("my thing"), details = "for this reason")

  bench::mark(
    deprecate_soft("1.1.0", I("my thing"), details = "for this reason")
  )
})

Can you make the condition object directly with structure()? (like simpleCondition())

[hadley]

Hmmm, and use signalCondition()?

See #195 for the fully lazy way
