Since [1] when the Dynamic Snippet was first introduced, it also
introduced a concept of "inherited" snippets. Specific snippets would
all `t-call` the same template for their rendering.
A mechanism was introduced to deduce the `data-snippet` from the caller
template, but it stored the obtained value in the `t-called` template
itself. Because of this if several "specific snippets" that used that
template had to be rendered, they would all have the `data-snippet`
value of the first one that got compiled.
We could compile the snippet template into something having a
dynamically obtained `data-snippet` value, but then that would be
equivalent to just using a `t-attf-data-snippet`.
All specific snippets already do set a `snippet_name` in the context
because it needs to be added in the classes.
This commit therefore adds a `t-att-data-snippet` attribute on the
base template, and populates with that same value in `onBuilt` for
stable versions.
During forward ports across stable versions, each new caller must be
patched as well - and all patches must be removed in master.
