Multi-dimensional array support in safe struct generator

[nima-davari-huawei]

The safe struct generator assumes len(member.fixedSizeArray) is always 1, and it does not handle multi-dimensional arrays properly. Here is an example:

• float matrix[4][4];

This MR adds a new code branch to handle such cases. Here is an example of what the new code would generate for the above example.

Before MR:

for (uint32_t i = 0; i < 4; ++i) {
    matrix[i] = in_struct->matrix[i]; // Does not compile
}

After MR:

for (uint32_t i0 = 0; i0 < 4; ++i0) {
    for (uint32_t i1 = 0; i1 < 4; ++i1) {
        matrix[i0][i1] = in_struct->matrix[i0][i1];
    }
}

Note that no auto-generated code needs to be checked in with the MR as it does not affect any existing structs.

@nima-davari-huawei thanks, now it will be simpler when you need this for future extensions!
