main: rewrite help message

This commit aims several goals.

First, we're going to recommend `tt` as a tool to run and manage
tarantool instances. The tool is going to replace `tarantoolctl` and it
seems valuable to sync recipes across different parts of the
documentation (including this help message).

Second, the action options and modifier options are separated now. At
least one action option should be specified. I hope, it is more obvious
from the help message now.

Third, single line descriptions are replaced with a bit more extended
ones to give a user basic context to understand an influence of an
option.

Updated the man page accordingly: synchronized the options, removed
`tarantoolctl`.

Part of #8862

NO_TEST=the help message is not an API for a developer
NO_CHANGELOG=nothing new here, just better wording here and there

@TarantoolBot document
Title: Update CLI options documentation

https://www.tarantool.io/en/doc/latest/reference/configuration/#command-options
seems to need an update. See the linked commit for details and updated
`tarantool --help` message.
