Add template parameter debuginfo to generic types

This changes debuginfo generation to add template parameters to
generic types.  With this change the DWARF now has
DW_TAG_template_type_param for types, not just for functions, like:

 <2><40d>: Abbrev Number: 6 (DW_TAG_structure_type)
    <40e>   DW_AT_name        : (indirect string, offset: 0x375): Generic<i32>
    <412>   DW_AT_byte_size   : 4
    <413>   DW_AT_alignment   : 4
...
 <3><41f>: Abbrev Number: 8 (DW_TAG_template_type_param)
    <420>   DW_AT_type        : <0x42a>
    <424>   DW_AT_name        : (indirect string, offset: 0xa65e): T

Closes #9224
