patch 9.2.0225: runtime(compiler): No compiler plugin for just

Problem:  runtime(compiler): No compiler plugin for just
Solution: Add a compiler plugin for the just command runner, add a test
          (Aditya Malik)

Sets makeprg and a custom errorformat to parse just's multi-line
error output into quickfix entries with file, line, column, and
message. Includes a test.

closes: #19773
