cmd: version: Get information about GCC and LD back

U-Boot version command is no longer showing information about GCC and LD.
The reason is that version.h has been removed that's why CC_VERSION_STRING
and LD_VERSION_STRING are not pass.
Values are generated to generated/version_autogenerated.h which is sourced
in version.h.

Fixes: 54ecce2cbf90 ("version: Separate our version string from the version command")
