token_range_vector is a sequence of intervals of tokens. It is used to describe vnodes or token ranges owned by shards. Since tokens are bloated (16 bytes instead of 8), and intervals are bloated (40 byte of overhead instead of 8), and since we have plenty of token ranges, such vectors can exceed our allocation unit of 128 kB and cause allocation stalls. This series fixes that by first generalizing some helpers and then changing token_range_vector to use chunked_vector. Although this touches IDL, there is no compatibility problem since the encoding for vector and chunked_vector are identical. There is no performance concern since token_range_vector is never used on any hot path (hot paths always contain a partition key). Fixes #3335. Fixes #24115. Fixes #24156 Backport notes: Due to compiler limitations in this toolchain, the template template parameters were replaced by elaborate template metaprogramming, see patch 'partition_range_compat: generalize wrap/unwrap helpers'.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
