metal : add FA kernels for HSK=96, HSV=64 (MiniCPM3) (#28599)
* metal : add FA kernels for HSK=96, HSV=64 (MiniCPM3)
MiniCPM3 sets attention.key_length to 96 and does not set
attention.value_length, which defaults to n_embd / n_head = 64. Metal had no
(96, 64) instantiation, so -fa auto aborted on the missing
kernel_flash_attn_ext_vec_f16_dk96_dv64.
Instantiate the tile kernel at (96, 64) for every K/V type that already has
(96, 96), and the vec kernel for the NE=4 configurations. Of the NE values the
vec dispatch considers, only NE=4 works here, because NL = 32/NE has to divide
both DK/4 = 24 and DV/4 = 16.
* tests : avoid redundant FA vec slice coverage
