Add lrm autogenerated transitional independent of variants

[Kleber Sacilotto de Souza]

[Impact]

The kernel lrm packages have a mechanism to auto-generate transitional packages by adding a line to 'debian/package.config' in the following format

transitional <from> <to> <archs>

Example:

transitional 450-oem-20.04 450-generic amd64

When being processed by 'debian/scripts/gen-rules.lrm' the autogenerated contents are added to 'debian/control.d/transitionals-local'. However, this file is not included in the final 'debian/control' for packages which does not contain the default variant '--' (see debian/rules.in). This is intentional to prevent unwanted transitionals.

However, there are some cases where we want to transition packages to kernels which are not the default variant in a series (e.g. hwe kernels).

[Fix]

The proposed fix is to add a new command "migrate", which does exactly what "transitional" does but adding the content to 'debian/control.d/migrate-local' which would get added to the final 'debian/control' independently of the source's variants.

[Test Case]

Add "migrate" entries to 'debian/package.config' and check whether they get added to 'debian/control' even for non default variant packages.

[Where problems could occur]

If not used correctly, unwanted transitionals could be generated causing issues to the archive. However, this is a new command and should not impact any of the previously set transitionals and it needs to be explicitly used.
