Upgrade Glutin to v0.19.0

Some changes include:

• Use the with_hardware_acceleration function on the ContextBuilder to not require the discrete GPU
• Remove the LMenu and RMenu virtual key codes (winit 0.16.0 removed these because Windows now generates LAlt and RAlt instead
• Replace set_cursor_state with hide_cursor (winit 0.16.0 removed the set_cursor_state function)
• Replace GlWindow::hidpi_factor with GlWindow::get_hidpi_factor and change to expecting an f64
• Use the glutin/winit dpi size and position types where possible

Glutin's dpi change event has been implemented. All size events now
return logical sizes. As a result of that, the logical sizes are translated
in the `display::handle_rezize` method so DPI scaling works correctly.

When the DPI is changed, the glyph cache is updated to make use of the
correct font size again.

Moving a window to a different screen which is a different DPI caused a
racing condition where the logical size of the event was sent to the
`handle_resize` method in `src/display.rs`, however if there was a DPI
change event before `handle_resize` is able to process this message, it
would incorrectly use the new DPI to scale the resize event.

To solve this issue instead of sending the logical size to the
`handle_resize` method and then converting it to a physical size in
there, the `LogicalSize` of the resize event is transformed into a
`PhysicalSize` as soon as it's received. This fixes potential racing
conditions since all events are processed in order.

The padding has been changed so it's also scaled by DPR.

The `scale_with_dpi` config option has been removed. If it's not present
a warning will be emitted.

The `winit` dependency on Windows has been removed. All interactions
with winit in Alacritty are handled through glutin.
