multilib_global.bbclass: PREFERRED_PROVIDERS for multilibs

The code in base.bbclass to spread PREFERRED_PROVIDERS values
to multilibs doesn't work for things which rely on TARGET_PREFIX,
such as virtual/${TARGET_PREFIX}gcc. This is because the expansion
of TARGET_PREFIX produces the wrong value if executed prior to
the assignment of TARGET_VENDOR_virtclass-multilib-libxx, which
will always happen since that assignment doesn't happen until recipe
parsing, but the PREFERRED_PROVIDERS expansion is happening
around ConfigParsed.

To solve this, we make a couple of changes. First, the creation
of the TARGET_VENDOR override values is moved into a new ConfigParsed
event handler in multilib_global. Second, the preferred_ml_updates()
function's code is moved into that function too. It seems safe to
assume that PREFERRED_PROVIDER values only need to be spread to
other multilibs when multilibs are in use.

I don't think this directly affects any use cases that don't involve
third-party or alternative toolchains.
