common : relax sampler name matching (#23744)

• common : relax sampler name matching

Currently, in some cases, the alternative names for samplers (like top-k and min-p instead of the canonical top_k and min_p) are not always recognized by the common_sampler_types_from_names function in common/sampling.cpp.

This PR changes the signature of this function to remove the bool allow_alt_names flag, and removes all occurences of the flag from call sites. Therefore, the function will now always match all known names.

I also changed the logic of the function to unconditionally check the provided sampler names against both the canonical and alternative names, and to be case-insensitive.

This fixes an issue I was seeing wherein samplers specified in the llama-server UI were not recognized as valid when the alternative names were used.

• add more alt names

• cont. fix

• cast to unsigned char for correctness

• common : unify sampler name mapping

• annotate canonical vs. alt sampler name mappings per @CISC

• Update common/sampling.cpp

• common : auto-generate sampler name aliases per @ngxson

• use merged map for matching

• use .merge instead of iterating

• nit: simplify comment

• nit: use insert everywhere, not index assignment
