fix(@angular-devkit/build-angular): workaround for esbuild static blo…

…ck AOT generated code

esbuild currently has a defect involving self-referencing a class within a static code block or
static field initializer. This is not an issue for projects that use the default browserslist as these
elements are an ES2022 feature which is not support by all browsers in the default list. However, if a
custom browserslist is used that only has newer browsers than the static code elements may be present.
This issue is compounded by the default usage of the tsconfig `"useDefineForClassFields": false` option
present in generated CLI projects which causes static code blocks to be used instead of static fields.
esbuild currently unconditionally downlevels all static fields in top-level classes so to workaround the
Angular issue only static code blocks are disabled here.

Fixes #25127
