bug(COMPONENT): Global density cant be set in angular material 15 mdc

### Is this a regression?

- [ ] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

v14.2.7

### Description

New input fields appear super big compared to previous versions.

Setting global density does not work:

@include mat.all-component-densities('maximum');
or
@include mat.all-component-densities(-3);

or setting it directly inside the theme.

It all does not have any effect.

### Reproduction

Steps to reproduce:
1. use angular material 15
2. use any kind of text input
3. try making it smaller by setting global density higher

### Expected Behavior

Form fields scaling up or down in size

### Actual Behavior

No effect

### Environment

- Angular: 15.0.3
- CDK/Material: 15.0.2
- Browser(s): Chrome
- Operating System (e.g. Windows, macOS, Ubuntu): macOS

Start by reproducing the issue in Angular 15 with a text input and the documented mat.all-component-densities mixin, including the theme-level setting. Trace the density and theme entry points to determine why the setting has no effect; done means form fields visibly scale up or down as expected.
