Support for more variants of 2d block reads

This change extends the implementation of `cl_intel_subgroup_2d_block_io`
extension with the following builtins:
```c
intel_sub_group_2d_block_read_8b_16r32x1c
intel_sub_group_2d_block_read_8b_32r32x1c

intel_sub_group_2d_block_read_32b_1r16x1c
intel_sub_group_2d_block_read_32b_2r16x1c
intel_sub_group_2d_block_read_32b_4r16x1c
intel_sub_group_2d_block_read_32b_8r16x1c
intel_sub_group_2d_block_read_32b_16r16x1c
intel_sub_group_2d_block_read_32b_32r16x1c

intel_sub_group_2d_block_prefetch_8b_16r32x1c
intel_sub_group_2d_block_prefetch_8b_32r32x1c

intel_sub_group_2d_block_prefetch_32b_1r16x1c
intel_sub_group_2d_block_prefetch_32b_2r16x1c
