targets: Finalize SoCs for LitePCIe driver exports

LitePCIe board targets only ran Builder when --build was passed. Using --driver alone could therefore generate driver files from an unfinalized SoC, leaving CSR/header data incomplete.

Run the Builder export/finalization step for LitePCIe driver or header generation too. When --build was not requested, disable software and gateware compilation first so this behaves like an automatic --build --no-compile export step.

Also create the output directory for the header-only LitePCIe generation paths before writing headers.

Tested with:
- python3 litex_boards/targets/xilinx_ac701.py --with-pcie --driver --output-dir=/tmp/litex1416-ac701-patched
- python3 litex_boards/targets/sipeed_tang_mega_138k.py --with-pcie --output-dir=/tmp/litex1416-tang138k-patched2
- git diff --check
- ast.parse() over all modified target files
