Using a custom Xtensa configuration requires an overlay that provides
that configuration; not providing an overlay is like using the default
configuration, BR2_xtensa_fsf, so there would be no point in that case
in requesting a custom configuraiton.
Make providing an overlay mandatory for custom configurations.

Xtensa core configuration must be added to U-Boot before it can be
built for that xtensa CPU variant. Extract configuration files from the
xtensa overlay as is done for other packages that need to be configured
for a specific xtensa core.

It can be interesting to get the overlay from a remote server, rather
than expect it to be present locally.
Since that file can be any URL, we can't know its hash, so we just
exclude it.

currently, specifying a custom Xtrensa core is done with two variables:
- the core name
- the directory containing the overlay tarball
However, the core name only serves to construct the tarball name, and is
not used whatsoever to configure any of the toolchain components
(binutils, gcc or gdb), except through the files that are overlayed in
their respective source trees.
This has two main drawbacks:
- the overlay file must be named after the core,
- the tarball can not be compressed.
Furthermore, it also makes it extremely complex to implement a download
of that tarball.
So, those two variables can be squeezed into a single variable, that is
the complete path of the overlay tarball.
Update the qemu-xtensa defconfig accordingly.
Note: we do not add a legacy entry for BR2_XTENSA_CORE_NAME, since it
was previously a blind option in the last release, and there's been no
release since we removed BR2_XTENSA_CUSTOM_NAME. So, we just update the
legacy comments for BR2_XTENSA_CUSTOM_NAME, since that's all the user
could have seen in any of our releases so far.

Currently, we have four packages that need to use the Xtensa overlay:
binutils, gcc-initial, gcc-final and gdb. However, they all use three
different ways to check for, and use the overlay. Furthermore, two of
them define the same variable: XTENSA_CORE_NAME is defined both by
binutils and gdb
In order to sanitise that, have the Xtensa architecture export the
appropriate variables: the name of the core and the path to the overlay
tarball. Packages can then check and use those variables.
