[llvm-debuginfo-analyzer] Add support for DWARF DW_AT_byte_size (llvm#139110)
This PR was split from llvm#137228 (which introduced support for `DW_TAG_module` and `DW_AT_byte_size`). This PR improves `LVDWARFReader` by introducing handling of `DW_AT_byte_size`. Most DWARF emitters include this attribute for types to specify the size of an entity of the given type.
