nir/linker: Fill TOP_LEVEL_ARRAY_SIZE and STRIDE

nir/linker: Fill TOP_LEVEL_ARRAY_SIZE and STRIDE

From the ARB_program_interface_query specification:

    "For the property TOP_LEVEL_ARRAY_SIZE, a single integer
    identifying the number of active array elements of the top-level
    shader storage block member containing to the active variable is
    written to <params>.  If the top-level block member is not
    declared as an array, the value one is written to <params>.  If
    the top-level block member is an array with no declared size, the
    value zero is written to <params>."

    "For the property TOP_LEVEL_ARRAY_STRIDE, a single integer
    identifying the stride between array elements of the top-level
    shader storage block member containing the active variable is
    written to <params>.  For top-level block members declared as
    arrays, the value written is the difference, in basic machine
    units, between the offsets of the active variable for consecutive
    elements in the top-level array.  For top-level block members not
    declared as an array, zero is written to <params>."
