Currently, if you have an ion-virtual-scroll with a list of items and a search bar for filtering them, when you change the list of items, the items disappear until rendered again, causing a flicker. This could be solved for the items using the itemHeight function to provide the exact height size and bypass some calculations and be more performant etc.
However, if you had a header or footer, they would still flicker. This commit adds two more optional functions named headerHeight and footerHeight that return the exact size of the header and footer respectively and resolve the flicker.
- Adds `ionImgWillLoad` event that emits when the img src is set
- Moves the `ionImgDidLoad` event emit so that it happens when the image actually finishes loading

Adds a `header` and `buttons` property to toast. This allows for a toast header to be passed and multiple buttons including action buttons and icon only buttons which matches the Material Design spec. Adds hover states to the button to match the spec. Updates usage section to recommend the new way of passing a close button using the buttons array and `cancel` role. If a button is passed using the cancel role default the color to match the spec. Buttons will default to the `end` side but have the option of being placed on the `start` side.

BREAKING CHANGES
## Core Components
Removes the `--width` and `--height` variables from the following components, in favor of CSS:
- Button
- FAB Button
- Checkbox
- Removes the `--width`/`--height` and adds a `--size` variable that is set on the width and height, allowing width and height to still be set and border-radius to still use it as a variable
- Radio
- Removes the `--width`/`--height` and `--inner-width`/`--inner-height` variables. Calculates inner values based on parent element size.
## Overlay Components
The following components have all be converted to shadow (or scoped) and have CSS variables for width/height:
- Action Sheet _(scoped)_
- Alert _(scoped)_
- Loading _(scoped)_
- Menu _(shadow)_
- Modal _(scoped)_
- Picker _(scoped)_
- Popover _(scoped)_
- Toast _(shadow)_
The above components will now have the following CSS variables for consistency among overlays:
| Name |
| ----------------- |
| `--height` |
| `--max-height` |
| `--max-width` |
| `--min-height` |
| `--min-width` |
| `--width` |
If the component does not set the value, it will default to `auto`.
