GH-14981: [R] Forward compatibility with dplyr::join_by()

[ianmcook]

Which issue does this PR close?

Closes#14981

Rationale for this change

dplyr 1.1.0 introduces a new function join_by() for specifying join conditions. This PR adds support for join_by() in dplyr joins on Arrow objects. The support is limited only to equality conditions. Code added in this PR throws an error if the user specifies inequality conditions or uses helper functions in join_by().

https://www.tidyverse.org/blog/2022/11/dplyr-1-1-0-is-coming-soon/#join-improvements

What changes are included in this PR?

• Code to handle join_by() in dplyr joins on Arrow objects with equality conditions
• Tests of handling of join_by(), which are skipped when the version of dplyr is less than 1.0.99.9000 which is the current version number of the development version of dplyr on GitHub which that become version 1.1.0 on CRAN.

Are these changes tested?

Yes

Are there any user-facing changes?

Yes, the new dplyr syntax for specifying join conditions is supported, but use of this new syntax is optional. The old dplyr join syntax will continue to work. There are no breaking changes in this PR.
