Initialization speed and pre-processing progress messages

targets 1.11.3

Bug fixes

• Use qmethod = "escape" to avoid Rdatatable/data.table#3509 (#1480, @koefoeden).
• Ensure error = "trim" does not hang when the errored target has a long chain of reverse dependencies (#1481, @koefoeden).
• Manually remove class "rlib_error_package_not_found" from errors (#1484, @malcolmbarrett). This and #1354 are unfortunate consequences of #997.

Other changes

• Call suppressPackageStartupMessages() once for the whole pipeline. Repeated target-specific calls may be slow, and the messages themselves are cumbersome. This is an appropriate tradeoff.
• Ensure the progress bar from the balanced reporter does not chop up messages from tar_debug_instructions().
• Remove ANSI escape sequences from warnings and error messages.
• Use cli::cli_text() instead of cli::cli_progress_output() (#1478, @dipterix).
• Minor speedups in the beginning and end of tar_make() (#1482).
• Cache _targets/objects/ time stamps only for local builders mentioned in the metadata, as opposed to everything in that directory (#1482).
• Instrument pre-processing overhead with progress bars (#1482).
