Move styles to the Angular Material 15 MDC components

Rewrites stylesheets and inline styles metadata for the MDC-based components of Angular Material 15, as the mdc-migration schematic does, in projects that are not on Material 15 yet: renames selectors of classes the MDC components renamed, such as .mat-form-field to .mat-mdc-form-field, renames the typography classes to the 2018 type scale, and includes the themes that the MDC components rely on, such as mat.fab-theme and mat.icon-button-theme next to mat.button-theme.
