Fix Makefile build: register new sources and resolve VPATH conflicts

Makefile.Objects:
- Register the new .cpp files split in this PR in their object groups
- Fix dangling entries: xc_funct_hcth.o -> xc_hcth.o, remove
  onsite_proj_pw.o, memory.o -> memory_recorder.o, dftu.o ->
  dftu_lcao.o and other renamed leftovers
- Update VPATH for renamed directories (source_lcao/module_hcontainer
  and module_gint moved to source_hamilt, add source_io subdirectories)
- Add an explicit symm_rho_charge.o rule target for
  source_estate/module_charge/symm_rho.cpp: two symm_rho.cpp files
  share the name and VPATH resolves to the source_cell one, leaving
  Symmetry_rho undefined (pre-existing on develop)
- Remove the duplicate setup_dftu_pw.o from OBJS_DFTU and drop the
  orphan dmr_complex.o, which no CMakeLists.txt compiles and which
  duplicates a DensityMatrix::cal_DMR specialization

Makefile:
- Set .DEFAULT_GOAL to abacus and pass -f to the sub-make so the
  default target actually builds instead of stopping after the first
  rule (the Intel Makefile CI job has been a 0-second no-op because
  the first rule only generated build_info.h)

generate_build_info.sh:
- Locate build_info.h.in relative to the script directory so the
  header is generated regardless of the caller's cwd

Verified: full GNU Make build with mpicxx links successfully; ABACUS.mpi
--version reports v3.11.0-beta8; tests/01_PW/101_PW_W90 runs to
completion with results matching result.ref; CMake xc_ target still
compiles on both libxc paths.
