Make BiosConfig run as one service.

As of now BiosConfig runs in two service as seen below.
1) xyz.openbmc_project.biosconfig_manager.service
busctl tree xyz.openbmc_project.BIOSConfigManager
`-/xyz
  `-/xyz/openbmc_project
    `-/xyz/openbmc_project/bios_config
      `-/xyz/openbmc_project/bios_config/manager

2) xyz.openbmc_project.biosconfig_password.service
busctl tree xyz.openbmc_project.BIOSConfigPassword
`-/xyz
  `-/xyz/openbmc_project
    `-/xyz/openbmc_project/bios_config
      `-/xyz/openbmc_project/bios_config/password

The code changes are to move functionalities of
xyz.openbmc_project.biosconfig_password.service to
xyz.openbmc_project.biosconfig_manager.service as
shown below

busctl tree xyz.openbmc_project.BIOSConfigManager
`-/xyz
  `-/xyz/openbmc_project
    `-/xyz/openbmc_project/bios_config
      |-/xyz/openbmc_project/bios_config/manager
      `-/xyz/openbmc_project/bios_config/password

Tested:
Made sure BiosConfig functionality is not affected.
Note that calls from bmcweb will now require to use
service as xyz.openbmc_project.biosconfig_manager.service
