Adds support for TypeScript 4.4. High-level overview of the changes made in this PR: * Bumps the various packages to `typescript@4.4.2` and `tslib@2.3.0`. * The `useUnknownInCatchVariables` compiler option has been disabled so that we don't have to cast error objects explicitly everywhere. * TS now passes in a third argument to the `__spreadArray` call inside child class constructors. I had to update a couple of places in the runtime and ngcc to be able to pick up the calls correctly. * TS now generates code like `(0, foo)(arg1, arg2)` for imported function calls. I had to update a few of our tests to account for it. See https://github.com/microsoft/TypeScript/pull/44624. * Our `ngtsc` test setup calls the private `matchFiles` function from TS. I had to update our usage, because a new parameter was added. * There was one place where we were setting the readonly `hasTrailingComma` property. I updated the usage to pass in the value when constructing the object instead. * Some browser types were updated which meant that I had to resolve some trivial type errors. * The downlevel decorators tranform was running into an issue where the Closure synthetic comments were being emitted twice. I've worked around it by recreating the class declaration node instead of cloning it. PR Close #43281 |

Angular Compatibility Compiler (ngcc)
This compiler will convert node_modules compiled with ngc, into node_modules which
appear to have been compiled with ngtsc.
This conversion will allow such "legacy" packages to be used by the Ivy rendering engine.
Building
The project is built using Bazel:
yarn bazel build //packages/compiler-cli/ngcc
Unit Testing
The unit tests are built and run using Bazel:
yarn bazel test //packages/compiler-cli/ngcc/test
Integration Testing
There are tests that check the behavior of the overall executable:
yarn bazel test //packages/compiler-cli/ngcc/test:integration
