feat(core): add dynamic queries schematic (#32231)

Adds a schematic that will remove the explicit `static: false` flag from dynamic queries. E.g.

```ts
import { Directive, ViewChild, ContentChild, ElementRef } from '@angular/core';

@Directive()
export class MyDirective {
  @ViewChild('child', { static: false }) child: any;
  @ViewChild('secondChild', { read: ElementRef, static: false }) secondChild: ElementRef;
  @ContentChild('thirdChild', { static: false }) thirdChild: any;
}
```

```ts
import { Directive, ViewChild, ContentChild, ElementRef } from '@angular/core';

@Directive()
export class MyDirective {
  @ViewChild('child') child: any;
  @ViewChild('secondChild', { read: ElementRef }) secondChild: ElementRef;
  @ContentChild('thirdChild') thirdChild: any;
}
```

+## Dynamic queries migration
+
+Automatically migrates dynamic queries to remove their `static` flag. This flag will no
+longer be necessary in version 9 for dynamic queries, as `false` is the default value.
+
+#### Before
+```ts
+import { Directive, ViewChild, ContentChild, ElementRef } from '@angular/core';
+
+@Directive()
+export class MyDirective {
+  @ViewChild('child', { static: false }) child: any;
+  @ViewChild('secondChild', { read: ElementRef, static: false }) secondChild: ElementRef;
+  @ContentChild('thirdChild', { static: false }) thirdChild: any;
+}
+```
+
+#### After
+```ts
+import { Directive, ViewChild, ContentChild, ElementRef } from '@angular/core';
+
+@Directive()
+export class MyDirective {
+  @ViewChild('child') child: any;
+  @ViewChild('secondChild', { read: ElementRef }) secondChild: ElementRef;
+  @ContentChild('thirdChild') thirdChild: any;
+}
+```
