The logic for the `elementStart` and `elementContainerStart` instructions was identical. These changes consolidate it into a single base instruction.

A minor performance improvement for `ɵɵdefineComponent` where the underlying `extractDefListOrFactory` call had a chain of `.map.filter` which meant that we were unnecessarily creating intermediate arrays just to filter out the null values. These changes switch to simple `for` loop to get around it.

After nearly a decade of existence, there are 0 uses of
`autoDetectChanges(false)` internally. All uses of
`autoDetectChanges(true)` can be migrated directly to
`autoDetectChanges()` instead.

Adds `__PURE__` annotations to non-default `new` expressions to enable tree-shaking, even if they are not referenced. These variables are not dropped when Angular is imported from a module that has `sideEffects` set to `true`.

Since the duplication root-cause was solved by the previous commit, we
can revert/drop the logic that was added back then to overcome this
problem with Tsurge.

Currently there can be cases, exlusively in 3P, where multiple tsconfig
projects have overlap of source files. This is the default setup of new
CLI applications as well.
When this is the case, Tsurge will treat each tsconfig as an isolated
compilation unit (given the concepts and mental model to support
scalable batching). This is wrong though, and the same `.ts` source file
can appear in two migration invocations; resulting in duplicate
replacements or analysis (depending on the migration).
We've worked around this problem in the past by deduplicating
replacements, or migrating to an ID-based approach with natural
deduplication. This worked, but it's just working around the root cause.
This commit attempts to fix the root cause by adjusting Tsurge to ensure
that no source file ever appears in two compilation units. This is
naively achieved by not adding a source file to a migration unit, if it
was part of a previous one. This is expected to be fine given the nature
of Tsurge migrations that are built to operate on isolated pieces
anyway— so it shouldn't be problematic if e.g. `app.component.ts` ends
up being part of the test tsconfig compilation unit (we avoid this order
though by visiting build targets first).

Fixes the `update_all_goldens` script which was throwing, because the query command was also capturing the call into yarn and Bazel which in turn caused it to throw an error. I've also added some validation for the number of targets.

Migrates `packages/core/schematics` to `ts_project`. As part of this,
this commit cleans up some of the mixed module types and tsconfigs in
the folder. A single tsconfig (and it's test variant) are now used.
For the shipped schematics, we explicitly use the `.cjs` extension, so
that the bundles are properly recognized as CommonJS; even if they are
part of the `type: module` `@angular/core` package.
The `package.json` with `type: commonjs` is removed from
`packages/core/schematics` as it's no longer needed given the explicit
extension & caused issues as schematics are compiled with ESM but are
only later bundled for shipping & some tests as ESM.

As we migrate more and more code to `ts_project`, we are ending up with
`.js` file extensions (ts_library did generate `.mjs` magically).
Since we don't want to get into the business of migrating
`nodejs_binary` targets at this point (in some cases we might)— we
should support pointing to such files.

The `getBaseHref` method is called several times per request and currently queries through the entire document. We can speed it up by taking advantage of the fact that the `<base>` can only be a direct child of the `<head>` and is usually defined towards the beginning. Below are some benchmarks for a "Hello world" app before and after this change.

This prevents `core/testing` from throwing an error if ZoneJS is present
but does not patch the test FW APIs such that `fakeAsync` works
automatically. For example, there is currently no patching of the vitest
APIs, so if you try to use Vitest with Zone on the page, it will throw.

There were a myriad of problems when using the type: 'cli' for a
tutorial:
* Editor component would flicker the non-cli version first since that
was the default value. Fixed by not showing anything until type is
available
* Editor component still rendered a split screen when there was no
preview. Fixed
* Project initialization was incorrect because the terminal would appear
to be available but really didn't work until dependencies were done
installing. Fixed by sharing initialization with regular project init
and piping the install output to the interactive terminal
* Terminals would not work when going from type: 'cli' to another or
vice versa. This is because the element instance of a terminal cannot
change once it is opened. Fixed by dispoing and recreating terminals
when the element changes
