Subject: [PATCH] The ValKind::operator<< uses ostream, but the include was
 missing. ostream is used so commonly that it's usually included by some other
 header. However, if you use wasmtime.hh as your first (or only) include, then
 you get a massive compile error on Apple toolchain compilers (I'm using xcode
 16). The error does not reproduce on Linux. (#60)

The error when this include is missing is:
```
include/wasmtime.hh:519:32: error: invalid operands to binary expression ('std::ostream' (aka 'basic_ostream<char>') and 'const char[4]')
  519 |     WASMTIME_FOR_EACH_VAL_KIND(CASE_KIND_PRINT_NAME)
third-party/wasmtime-cpp/include/wasmtime.hh:504:3: note: expanded from macro 'WASMTIME_FOR_EACH_VAL_KIND'
  504 |   X(I32, "i32", WASM_I32)                                                      \
      |   ^~~~~~~~~~~~~~~~~~~~~~~
third-party/wasmtime-cpp/include/wasmtime.hh:517:8: note: expanded from macro 'CASE_KIND_PRINT_NAME'
  517 |     os << name;                                                                \
```
