Bill Hollings 3d4daab29d MSL: Support input/output blocks containing nested struct arrays
Fixes numerous CTS tests of types
dEQP-VK.pipeline.interface_matching.vector_length.member_of_*,
passing complex nested structs between stages as stage I/O.

- Make add_composite_member_variable_to_interface_block() recursive to allow
  struct members to contain nested structs, building up member names and access
  chains recursively, and only add the resulting flattened leaf members to the
  synthetic input and output interface blocks.
- Recursively generate individual location numbers for the flattened members
  of the input/output block.
- Replace to_qualified_member_name() with append_member_name().
- Update add_variable_to_interface_block() to support arrays as struct members,
  adding a member to input and output interface blocks for each element of the array.
- Pass name qualifiers to add_plain_member_variable_to_interface_block() to allow
  struct members to be arrays of structs, building up member names and access chains,
  and adding multiple distinct flattened leaf members to the synthetic input and
  output interface blocks.
- Generate individual location numbers for the individual array members
  of the input/output block.
- SPIRVCrossDecorationInterfaceMemberIndex references the index of a member
  of a variable that is a struct type. The value is relative to the variable,
  and for structs nested within that top-level struct, the index value needs
  to take into consideration the members within those nested structs.
- Pass var_mbr_idx to add_plain_member_variable_to_interface_block() and
  add_composite_member_variable_to_interface_block(), start at zero for each
  variable, and increment for each member or nested member within that variable.
