ggml : fix BLAS with unsupported types (#9775) 
* ggml : do not use BLAS with types without to_float

* ggml : return pointer from ggml_internal_get_type_traits to avoid unnecessary copies

* ggml : rename ggml_internal_get_type_traits -> ggml_get_type_traits

it's not really internal if everybody uses it

// This file defines tests for various GGML ops and backends.
// For the forward pass it asserts that the results of multiple backends computing the same GGML ops are consistent.
// For the backward pass it asserts that the gradients from backpropagation are consistent
// with the gradients obtained via the method of finite differences ("grad" mode, this is optional).
// It is also possible to check the performance ("perf" mode).
//
// this file has three sections: Section 1 does general setup, section 2 defines the GGML ops to be tested,
// and section 3 defines which tests to run.
// Quick start for adding a new GGML op: Go to section 2 and create a struct that inherits from test_case,
// then go to section 3 and add an instantiation of your struct.
