Problem: Modula2 filetype support lacking
Solution: Improve the Modula-2 runtime support, add additional modula2
dialects, add compiler plugin, update syntax highlighting,
include syntax tests, update Makefiles (Doug Kearns)

- Luaify the detection script:
- Split the `(*!m2foo*)` and `(*!m2foo+bar*)` detection into two Lua patterns,
as Lua capture groups cannot be used with `?` and friends (as they only work
on character classes).
- Use `vim.api.nvim_buf_call()` (ew) to call `modula2#SetDialect()` to ensure
`b:modula2` is set for the given bufnr.
- Skip the syntax screendump tests. (A shame as they test some of the detection
from `(*!m2foo+bar*)` tags, but I tested this locally and it seems to work)
- Port the synmenu.vim changes from Vim9 script. (Also tested this locally)
- (And also add the missing comma for `b:browsefilter` from earlier.)
