Introduce `StringConsts` (a `HashMap<&str, Ident>`) and `collect_string_consts`
to walk a program's top-level `const` declarations and capture literal string
values. Pass the map through `extract_directive_metadata`,
`extract_component_metadata`, and all helper functions so that identifier
references used as host-binding keys or values (e.g. `host: { [MARKER_ATTR]: '' }`)
are resolved to their string values at compile time, matching the official
Angular compiler's constant-folding behaviour.
Add integration tests covering identifier keys and identifier values in host
bindings for both directives and components.

The use of variables within decorators is not currently supported - this PR provides basic support for the use of variables in decorators. Currently this supports variables defined within the same file, e.g.
For full equivalent to Angular we would need to add resolving across multiple files, i.e. following imports - but that could be covered by a separate PR - this provides the initial basic support.
