For all parts of Bazel other than option parsing, string build setting flags with `allow_multiple = True` should behave just like `string_list` settings, even though they are fundamentally of a different type. This requires a lot of special casing all over the code base and also causes confusing user-facing behavior when transitioning on such settings. This commit deprecates the `allow_multiple` named parameter of `config.string` and as a replacement introduces a new named parameter `repeatable` on `config.string_list`. Settings with the latter set to True behave exactly like `string` settings with `allow_multiple = True` with respect to command-line option parsing and exactly like ordinary `string_list` flags in all other situations. Fixes bazelbuild#13817 Closes bazelbuild#14911. PiperOrigin-RevId: 462146752 Change-Id: I91ddc4328a1b2244f4303fcda7b4228b182a5d56
