  [macOS] Fix input[type=search] rendering in vertical writing mode

Reviewed by Tim Nguyen.

Native search fields are not height resizable, and have shadows,
preventing their use in vertical writing mode. Instead, fall back
to drawing native text fields, which are height resizable.

Additionally, ensure that the cancel and results buttons are displayed
correctly in vertical writing mode.

* Source/WebCore/html/shadow/TextControlInnerElements.cpp:

253691 at main introduced logic to hide the cancel and results buttons when
authors specify `appearance: textfield` on search inputs. Preserve this
functionality, but also allow cases where the user agent applies
`appearance: textfield` for rendering purposes (in this case, in vertical
writing mode), by comparing `appearance` in addition to `effectiveAppearance`.

(WebCore::searchFieldStyleHasExplicitlySpecifiedTextFieldAppearance):
(WebCore::SearchFieldResultsButtonElement::resolveCustomStyle):
(WebCore::SearchFieldCancelButtonElement::resolveCustomStyle):
* Source/WebCore/rendering/RenderTheme.cpp:
(WebCore::RenderTheme::adjustStyle):

Set an effective appearance of `TextField` for search fields using a vertical
writing mode.

* Source/WebCore/rendering/RenderTheme.h:
(WebCore::RenderTheme::searchFieldShouldAppearAsTextField const):
* Source/WebCore/rendering/RenderThemeMac.h:
* Source/WebCore/rendering/RenderThemeMac.mm:
(WebCore::RenderThemeMac::searchFieldShouldAppearAsTextField const):
(WebCore::RenderThemeMac::adjustSearchFieldDecorationPartStyle const):

While the results and cancel buttons are not being rotated, ensure there is not
an excessive amount of padding at the logical top of the control in cases where
the results button is hidden.
