This commit ensures that libraries can use signal-based queries, and the partial compilation output will capture their metadata. The linker is updated to support parsing this. Two notes: 1. Older linker versions are not capable of parsing this, so the minimum version for signal-based queries is adjusted when such are used. 2. We only emit `isSignal` metadata for queries when signal queries are used. This enables libraries to continue supporting older linker versions, if signal-based queries are not used. PR Close #53978 |

Angular Linker
This package contains a FileLinker and supporting code to be able to "link" partial declarations of components, directives, etc in libraries to produce the full definitions.
The partial declaration format allows library packages to be published to npm without exposing the underlying Ivy instructions.
The tooling here allows application build tools (e.g. CLI) to produce fully compiled components, directives, etc at the point when the application is bundled.
These linked files can be cached outside node_modules so it does not suffer from problems of mutating packages in node_modules.
Generally this tooling will be wrapped in a transpiler specific plugin, such as the provided Babel plugin.
Unit Testing
The unit tests are built and run using Bazel:
yarn bazel test //packages/compiler-cli/linker/test
