refactor(core): static-queries migration should never use ngtsc (#32954)

ec4381d enabled Ivy by default. This is problematic as migrations
like `static-queries` depend on the `AngularCompilerProgram` (NGC)
in order to perform the migration from version 7 to version 8.

In order to ensure that the migration always runs with NGC
(and doesn't get the `NgtscProgram`), we need to explicitly disable
ivy when creating the `@angular/compiler-cli` program for the migration.

This code is still relevant even though the update from version 7
to version 8 landed. Developers can run `ng update` from version 7
and immediately get to version 9 where Ivy is enabled by default (and in
that case we need to ensure that ngtsc is not accidentally used).

Similar to
