This is the first step of removing GlobalC::exx_info global variable.

## Changes
- Split Exx_Info into 4 independent header files:
  - exx_info_global.h: Exx_Info_Global (core global settings)
  - exx_info_lip.h: Exx_Info_Lip (LIP method parameters)
  - exx_info_ri.h: Exx_Info_RI (RI method parameters)
  - exx_info_opt_abfs.h: Exx_Info_Opt_ABFs (optimized ABF parameters)
- Modified exx_info.h to include the 4 new headers
- Updated all references from Exx_Info::Exx_Info_* to Exx_Info_*

## Benefits
1. Reduced coupling: modules can now include only needed headers
2. Types are now independent, preparing for parameter passing
3. GlobalC::exx_info remains unchanged, fully backward compatible

## Next Steps (Phase 2-3)
Phase 2: Replace references with value copies in Exx_Info_Lip/RI
  - Exx_Info_Lip: ccp_type& and hse_omega& -> value copies
  - Exx_Info_RI: coulomb_param& -> value copy
  - This removes dependency on Exx_Info_Global lifetime

Phase 3: Remove GlobalC::exx_info global variable
  - Pass Exx_Info_* as parameters instead of global access
  - Update ~60 files that use GlobalC::exx_info
  - Modules: module_xc, module_ri, source_lcao, source_esolver, source_pw

## Changes

### 1. Modified struct definitions

**`exx_info_lip.h`**: Changed references to value copies
- `const Ccp_Type& ccp_type` → `Ccp_Type ccp_type`
- `const double& hse_omega` → `double hse_omega = 0.11`
- Removed constructor dependency on Exx_Info_Global

**`exx_info_ri.h`**: Changed reference to value copy
- `const std::map<...>& coulomb_param` → `std::map<...> coulomb_param`
- Removed constructor dependency on Exx_Info_Global

### 2. Added sync method in exx_info.h

```cpp
void sync_from_global()
{
    info_lip.ccp_type = info_global.ccp_type;
    info_lip.hse_omega = info_global.hse_omega;
    info_ri.coulomb_param = info_global.coulomb_param;
}
```

### 3. Added sync calls

| File | Location | Purpose |
|------|----------|----------|
| `input_conv.cpp` | Line 520 | After EXX parameter initialization |
| `esolver_lrtd_lcao.cpp` | Lines 266, 404 | After setting ccp_type |
| `RPA_LRI.hpp` | Line 148 | After setting ccp_type |

## Benefits

1. **Eliminated lifetime dependency**: Exx_Info_Lip and Exx_Info_RI are now independent
2. **Safe to copy/move**: No dangling reference risks
3. **Ready for parameter passing**: Structs can be safely passed as function parameters
4. **Fully backward compatible**: GlobalC::exx_info still exists and works unchanged

## Next Steps (Phase 3)

Remove GlobalC::exx_info global variable by:
- Passing Exx_Info_* structs as parameters
- Updating ~60 files that access GlobalC::exx_info
- Modules: module_xc, module_ri, source_lcao, source_esolver, source_pw
