b3ef15aa - [RISCV] Fix generation of DWARF info for vector segmented types (#137941)

[RISCV] Fix generation of DWARF info for vector segmented types (#137941) In DWARF info RISC-V Vector types are presented as DW_TAG_array_type with tags DW_AT_type (what elements does this array consist of) and DW_TAG_subrange_type. DW_TAG_subrange_type have DW_AT_upper_bound tag which contain upper bound value for this array. For now, it's generate same DWARF info about length of segmented types and their corresponding non-tuple types. For example, vint32m4x2_t and vint32m4_t have DW_TAG_array_type with same DW_AT_type and DW_TAG_subrange_type, it means that this types have same length, which is not correct (vint32m4x2_t length is twice as big as vint32m4_t)
