Makefile: add 'show-info-all'

Browse Source 
The maintenance and testing workflow sometimes requires to output a
list of every existing package on Buildroot:

- Generating an SBOM of the whole Buildroot tree, e.g. `for
  security.buildroot.org
- List every source for every package, e.g. for sources.buildroot.net

The previous solution relied on `make allyesconfig` but always ran into
conflicts that needed manual resolution. Also some packages would not be
present because they are architecture dependent.

To avoid having to manually modify the 'show-info' command this commit
adds the 'show-info-all' command. It accesses the PACKAGES_ALL variable
with all the packages present in Buildroot independently of the
architecture or any config entries.

It forces the `BR2_HAVE_DOT_CONFIG` variable to be set to force the
reading of the package mk files.

It is also added to noconfig_targets, to avoid the .config influencing
the output of show-info-all.

Note that this is not yet a complete solution - it doesn't take into
account the multiple versions that are possible for some packages like
GCC. Also for e.g. linux or uboot the version is empty and the URL is
invalid.
