scalar: add --no-tags option to 'scalar clone'

Browse Source 
Some large repositories use tags to track a huge list of release
versions. While this choice is costly on the ref advertisement, it is
further wasteful for clients who do not need those tags. Allow clients
to optionally skip the tag advertisement.

This behavior is similar to that of 'git clone --no-tags' implemented in
0dab2468ee (clone: add a --no-tags option to clone without tags,
2017-04-26), including the modification of the remote.origin.tagOpt
config value to include "--no-tags".

One thing that is opposite of the 'git clone' implementation is that
this allows '--tags' as an assumed option, which can be naturally negated
with '--no-tags'. The clone command does not accept '--tags' but allows
"--no-no-tags" as the negation of its '--no-tags' option.

While testing this option, combine the test with the previously untested
'--no-src' option introduced in 4527db8ff8 (scalar: add --[no-]src
option, 2023-08-28).
