bmcweb: enable google-baremetal for gbmc-baremetal

Platforms having bare-metal feature should only need to add:
- gbmc-baremetal to MACHINE_FEATURES in conf files.
- config the require setting in the setup bb file.

Tested:
```
// the option is still disabled for a random platform.
bitbake -e bmcweb | grep EXTRA_OEMESON=
... -Dgoogle-baremetal=disabled ...
// also no bare-metal-setup in `bitbake -e obmc-phosphor-image | grep
//  OBMC_IMAGE_EXTRA_INSTALL=`

// the option is enabled for a platform with adding machine features.
bitbake -e bmcweb | grep EXTRA_OEMESON=
...  -Dgoogle-baremetal=enabled ...
// also bare-metal-setup in `bitbake -e obmc-phosphor-image | grep
//  OBMC_IMAGE_EXTRA_INSTALL=`
```
