This change adds support for `pkg-config` to virtualenv by adding the virtual environment's `lib/pkgconfig` directory to the `PKG_CONFIG_PATH` environment variable upon activation. This is done for all supported shells: - Bash (`activate.sh`) - Batch (`activate.bat`, `deactivate.bat`) - C Shell (`activate.csh`) - Fish (`activate.fish`) - Nushell (`activate.nu`) - PowerShell (`activate.ps1`) - Python (`activate_this.py`) The implementation follows the style of the existing activation scripts for each shell, saving the original `PKG_CONFIG_PATH` on activation and restoring it on deactivation. Unit tests for each shell's activation have been updated to verify that `PKG_CONFIG_PATH` is set and unset correctly. Fixes pypa#2637

The activation scripts for bash and fish did not correctly handle the `PKG_CONFIG_PATH` environment variable when it was initially unset. This caused the variable to be set to an empty string after deactivation, instead of being unset. This commit fixes the activation scripts to correctly save and restore the `PKG_CONFIG_PATH`, and adds tests to verify the behavior.

The activation scripts for bash, fish, nushell, and powershell did not correctly handle the `PKG_CONFIG_PATH` environment variable when it was initially unset. This caused the variable to be set to an empty string after deactivation, instead of being unset. This commit fixes the activation scripts to correctly save and restore the `PKG_CONFIG_PATH`, and adds tests to verify the behavior. This ensures that the environment is restored to its original state after deactivation.
