Alex Rickabaugh b0578061ce refactor(ivy): use ɵɵ instead of Δ for now (#29850)
The `Δ` caused issue with other infrastructure, and we are temporarily
changing it to `ɵɵ`.

This commit also patches ts_api_guardian_test and AIO to understand `ɵɵ`.

/*
* This file exists to support compilation of @angular/core in Ivy mode.
*
* When the Angular compiler processes a compilation unit, it normally writes imports to
* @angular/core. When compiling the core package itself this strategy isn't usable. Instead, the
* compiler writes imports to this file.
*
* Only a subset of such imports are supported - core is not allowed to declare components or pipes.
* A check in ngtsc's `R3SymbolsImportRewriter` validates this condition. The rewriter is only used
* when compiling @angular/core and is responsible for translating an external name (prefixed with
* ɵ) to the internal symbol name as exported below.
*
* The below symbols are used for @Injectable and @NgModule compilation.
