Improve repl stack frame pretty printing

[jmcardon]

While working on separate PRs, I noticed that it is incredibly annoying to sometimes fail with large callstacks, so I've fixed this.

Take this repl file function that simply fails with a callstack:

(defun fails-with-args (a b c k)
  (enforce false "boom")
)

(fails-with-args "a1u23123uh123uh123uh123uh123uh123123" (^ 2 10) 20 (enumerate 1 100))

Before this PR, this fails with:

Loaded repl defun fails-with-args
scratch/kek.repl:23:2: boom
 23 |   (enforce false "boom")
    |   ^^^^^^^^^^^^^^^^^^^^^^
  at (#repl.fails-with-args "a1u23123uh123uh123uh123uh123uh123123" 1024 20 [ 1
, 2
, 3
, 4
, 5
, 6
, 7
, 8
, 9
...

(I cut the output, it goes from 1 to 100)

After this PR:

Loaded repl defun fails-with-args
scratch/kek.repl:23:2: boom
 23 |   (enforce false "boom")
    |   ^^^^^^^^^^^^^^^^^^^^^^
  at (#repl.fails-with-args "a1u23123uh12..." 1024 20 [1 2 3 4 5 6 ...])

PR checklist:

• [x] Test coverage for the proposed changes
• We don't test for repl error messages, they are not meant to be stable
• [x] PR description contains example output from repl interaction or a snippet from unit test output
• [x] (If Relevant) Documentation has been (manually) updated at https://docs.kadena.io/pact

Additionally, please justify why you should or should not do the following:

• [ ] Benchmark regressions
• [x] Confirm replay/back compat (Ignore until core release)
• [x] (For Kadena engineers) Run integration-tests against a Chainweb built with this version of Pact (Ignore until core release)
