[ET-VK][ez] Improve quantized convolution test case naming

[SS-JIA]

Stack from ghstack (oldest at bottom):

• [ET-VK] QConv: Avoid dynamic indexing of temporary arrays #16142
• -> [ET-VK][ez] Improve quantized convolution test case naming #16141

As title - update the way the test case names are displayed in the quantized convolution test binaries so that it is more clear what is being tested.

Before:

performance_64/32_128/128_3/3_Texture3D_Float

After:

PERF  32->64  I=128,128  k=3  Tex->Buf
