dundargoc 052498ed42 test: improve test conventions
Specifically, functions that are run in the context of the test runner
are put in module `test/testutil.lua` while the functions that are run
in the context of the test session are put in
`test/functional/testnvim.lua`.

Closes https://github.com/neovim/neovim/issues/27004.

-- Tests for autocommands
-- - FileWritePre writing a compressed file
-- - FileReadPost reading a compressed file
-- - BufNewFile reading a file template
-- - BufReadPre decompressing the file to be read
-- - FilterReadPre substituting characters in the temp file
-- - FilterReadPost substituting characters after filtering
-- - FileReadPre set options for decompression
-- - FileReadPost decompress the file
-- Note: This test is skipped if "gzip" is not available.
-- $GZIP is made empty, "-v" would cause trouble.
-- Use a FileChangedShell autocommand to avoid a prompt for "Xtestfile.gz"
