>+ [macOS] Cannot change font size at selection until font panel is shown

>+ Reviewed by Ryosuke Niwa.
>+
>+ Currently, attempting to alter the font size of currently selected editable text in WKWebView via menu items
>+ will fail if the font panel has never been shown. This is because WebViewImpl::changeFontFromFontPanel, which is
>+ responsible for converting the current font at the selection to the new font using -[NSFontManager convertFont:]
>+ bails as a result of NSFontManager's currently selected font always being nil.
>+
>+ WKWebView is responsible for keeping NSFontManager up-to-date with the currently selected font; in fact, this
>+ was initially the case in r180465, which introduced NSFontManager support in WebKit2 by propagating EditorState
>+ updates that contained font information for the current selection. However, this regressed performance due to
>+ selected font computation triggering extra layout passes; r180768 addressed this by introducing a mechanism for
>+ requesting the font at the current selection, and only updating NSFontManager with the new selected font when
>+ the shared font panel is visible (determined by KVO on NSFontPanel). However, this again regressed WKWebView
>+ launch performance, due to KVO registration always forcing the shared NSFontPanel to be created. r182037
>+ addressed this by only registering for KVO on the font panel if the WKWebView has been made editable (SPI on
>+ WKWebView).
>+
>+ This leads to two issues when attempting to alter font attributes using macOS UI: (1) in web views that have not
>+ been made editable using SPI, showing the font panel and attempting to change the font fails due to the selected
>+ font staying nil, because we've never begun registering for KVO notifications on the font panel so we don't try
>+ to keep the font manager up to date. (2) Even if the web view is made editable, if the font panel is never
>+ shown, then the font manager still won't be kept up to date with the current selection, so changing fonts using
>+ menu items still does not work.
>+
>+ We fix both of these problems by refactoring font manager support on WebKit2 such that an up-to-date selected
>+ font in the UI process is no longer necessary in order to alter the font at the current selection. To do this,
>+ we figure out what changes the NSFontManager would've made to the currently selected font in the UI process, and
>+ then propagate this information to the web process, where we convert this information into an EditingStyle which
>+ we apply to the current selection.
>+
>+ The code to both determine the attributes changed by NSFontManager and to convert these attributes into editing
>+ styles to be applied via Editor already exists in WebKitLegacy, in WebHTMLView.mm. This patch moves this
>+ existing logic into WebCore and teases it apart into two portions: the first portion probes NSFontManager to
>+ determine which aspects of the font changed and constructs FontChanges, which captures these differences. The
>+ second portion maps FontChanges to an EditingStyle, which can then be applied to the current selection. In
>+ WebKitLegacy, we construct FontChanges using the font manager, and then immediately use it to create and apply
>+ an EditingStyle. In WebKit, we construct FontChanges in the UI process using the font manager, and then send
>+ this over to the web process via WebPage::changeFont, which then creates and applies the EditingStyle.
>+
>+ Note that this patch also introduces FontAttributeChanges, which is similar in concept to FontChanges, but
>+ captures a broader range of changes possible via NSFontPanel. This was done so that we can eliminate all of the
>+ font manager probing code (along with the two specimen fonts) from WebHTMLView, but is also necessary in order
>+ to allow changing font shadow, strikethrough, and underlines via the font panel to work in WebKit2. This will be
>+ fixed in a followup, by making FontAttributeChanges IPC encodable and by making WKWebView/WKView respond to the
>+ -changeAttributes: selector.
>+
>+ Changes in behavior to WebKit2 are covered by new API tests; legacy WebKit behavior should remain unchanged.
