C API: Fix parameter type for compilation mode configuration

[turbolent]

Compiling against the current header produces:

# github.com/onflow/wasmi-go
In file included from ./config.go:4:
In file included from ./wasmi/include/wasmi.h:5:
./wasmi/include/wasmi/config.h:124:43: error: type specifier missing, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int]
  124 | WASMI_CONFIG_PROP(void, compilation_mode, wasmi_compilation_mode_enum)
      |                                           ^
      |                                           int
./wasmi/include/wasmi/config.h:17:66: note: expanded from macro 'WASMI_CONFIG_PROP'
   17 |   WASM_API_EXTERN ret wasmi_config_##name##_set(wasm_config_t *, ty);
      |

Fix the parameter type by adding the missing enum keyword. Alternatively maybe add a typedef for wasmi_compilation_mode_enum.

BTW, the comment for the function is also wrong (says " Whether or not to floating Wasm point types and operations are enabled." atm)

What would you say is a better practice in C headers?

@turbolent Thanks a lot for the fix!
