Details:
- Added missing 'restrict' keyword to cntx_t* argument of function
signatures corresponding to level-1v, level-1f, and level-1m kernels.
This affected bli_l1v_ker_prot.h, bli_l1f_ker_prot.h, and
bli_l1m_ker_prot.h. (The 'restrict' was already being used to
qualify cntx_t* arguments for kernels defined in bli_l3_ker_prot.h.)
- Added comments to bli_l1v_ker.h, bli_l1f_ker.h, bli_l1m_ker.h, and
bli_l3_ukr.h that help explain how those headers function to produce
kernel prototypes using the prototype macros defined in the files
mentioned above.
