This commit improves permission prompts by adding an option to print a full trace of where the permissions is being requested. Due to big performance hint of stack trace collection, this is only enabled when `DENO_TRACE_PERMISSIONS` env var is present. Closes https://github.com/denoland/deno/issues/20756 --------- Co-authored-by: Bartek Iwańczuk <biwanczuk@gmail.com>
