tests : link each test against only the libraries it uses (#30299)

Give llama_build() and llama_build_and_test() a LINK keyword (default:
llama-common) so call sites can declare what a test actually needs:

• ggml-only tests now link just ggml: test-opt, test-metal-graph-optimize,
  test-backend-ops, test-tiled-mulmat, test-barrier, test-quantize-fns,
  test-quantize-perf, test-rope, test-col2im-1d, test-gguf, test-alloc
• llama-only tests drop llama-common: test-unicode, test-sampling,
  test-grammar-parser, test-llama-grammar, test-batch-alloc,
  test-gbnf-validator, test-quant-type-selection
• both mtmd tests link mtmd only, dropping the LLAMA_TEST_NAME /
  target_link_libraries workarounds

Both helpers now set cxx_std_17 explicitly, since the tests no longer
inherit it from llama-common's PUBLIC interface.

tests/testing.h no longer includes common.h; the only symbol it used from
there (string_join) is inlined.
