If the underlying template name of a qualified template name is a using
decl, TemplateName::getAsUsingDecl() will return it.
This will make the UsingTemplateName consumer life easier.

This is the template version of https://reviews.llvm.org/D114251.
This patch introduces a new template name kind (UsingTemplateName). The
UsingTemplateName stores the found using-shadow decl (and underlying
template can be retrieved from the using-shadow decl). With the new
template name, we can be able to find the using decl that a template
typeloc (e.g. TemplateSpecializationTypeLoc) found its underlying template,
which is useful for tooling use cases (include cleaner etc).
This patch merely focuses on adding the node to the AST.
Next steps:
- support using-decl in qualified template name;
- update the clangd and other tools to use this new node;
- add ast matchers for matching different kinds of template names;

It breaks arm build, there is no free bit for the extra
UsingShadowDecl in TemplateName::StorageType.
Reverting it to build the buildbot back until we comeup with a fix.
This reverts commit 5a5be4044f.
