Remove use of Try::Tiny entirely (the missing part of ddcc02d1)

Remove use of Try::Tiny entirely (the missing part of ddcc02d1)

While at the time it seemed expedient to keep relying on Try::Tiny::catch and
only replace Try::Tiny::try internally, it turns out that the current naming
behavior of T::T [1] means we can not get DBIC::Carp to report a friendly
callsite, as finding which catch{} frames are skippable becomes problematic.

Additionally this drops a flurry of runtime Sub::Name calls which in turn
is likely to take less time ( note - this has not been explicitly timed, but
seems to pop up often in profiles: https://youtu.be/PYCbumw0Fis?t=1919 )

In any case - one less dep that we do not really use is always a win

Despite the large changeset there should be zero functional changes

This essentially reverts the entirety of 9b58d129
