gdb: Remove a use of VEC from dwarf2read.{c,h}
Removes a use of VEC from dwarf2read.{c,h} and replaces it with
std::vector. As far as possible this is a like for like replacement
with minimal refactoring.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* dwarf2read.c (struct type_unit_group) <tus>: Convert to
std::vector.
(build_type_psymtabs_reader): Update for std::vector.
(build_type_psymtab_dependencies): Likewise.
* dwarf2read.h: Remove use of DEF_VEC_P.
(typedef sig_type_ptr): Delete.
