Don't read 8 bytes from a 3-byte array

The elements of the av1_fwd_txfm_shift_ls array point to 3-byte (global)
arrays. It is unsafe to read from a 3-byte array using vld1_s8(), which
reads 8 bytes.

This bug was introduced when av1/encoder/arm/neon/av1_fwd_txfm2d_neon.c
was added in https://aomedia-review.googlesource.com/c/aom/+/110221.
ASan reported global-buffer-overflow errors.
