Igor Minar 4d0e175a65 fix(core): reenable decorator downleveling for Angular npm packages (#37317 )

In #37221 we disabled tsickle passes from transforming the tsc output that is used to publish all
Angular framework and components packages (@angular/*).

This change however revealed a bug in the ngc that caused __decorate and __metadata calls to still
be emitted in the JS code even though we don't depend on them.

Additionally it was these calls that caused code in @angular/material packages to fail at runtime
due to circular dependency in the emitted decorator code documeted as
https://github.com/microsoft/TypeScript/issues/27519.

This change partially rolls back #37221 by reenabling the decorator to static fields (static
properties) downleveling.

This is just a temporary workaround while we are also fixing root cause in `ngc` - tracked as
FW-2199.

Resolves FW-2198.

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
