This is a prerequisite for letting users add a Handlebars-based generator (e.g. a Markdown one) by dropping a template folder in an addon, without writing C++.
This moves `id`, `fileExtension`, and `displayName` from per-subclass virtual overrides to base-class members set through the constructor. That's a prerequisite for letting users add a Handlebars-based generator without writing C++.
The function was failing on `!file.good()` which includes the `eof()` case, so an empty file caused a failure. Test for "fail() but not just because we hit EOF", instead.
An <addon>/generator/<name>/ directory that ships at least one *.<name>.hbs layout is now installed as an additional `HandlebarsGenerator` at config-resolve time. An optional mrdocs-generator.yml next to the layouts supplies escape rules. This way, a generator can be added without writing any C++.
Generator lookup happened once at `TestRunner` construction. With addon-defined Handlebars generators now possible, a generator contributed via a test's `addons-supplemental` was unreachable from the test binary: the lookup ran before that test's mrdocs.yml had been loaded, so the generator wasn't yet registered. The runner now defers the lookup. The built-in generators are not affected.

This adds a fixture under test-files/template-only-generators/mock-md that ships its own mock "Markdown-like" generator via an addon-local `addons-supplemental`: a one-line layout that emits the symbol name, plus a single escape rule mapping `_` to `\_`.

This adds support for Handlebars-based generators that don't involve any C++ code. <addon>/generator/<name>/ directories are picked up at config-resolve time and installed as additional generators; escape rules can be provided via <name>/mrdocs-generator.yml.
