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
