Merge 94268 - REGRESSION(r88115): "Choose File" button doesn't respect font-size property for the <input>
https://bugs.webkit.org/show_bug.cgi?id=67181

Reviewed by Dimitri Glazkov.

Source/WebCore:

r88115 removed the code to make inherited style of the owner input
element, and html.css contains "font: -webkit-small-control" for
input element. So -webkit-file-upload-button always had
-webkit-small-control font.

Test: fast/forms/file/file-style-inheritance.html

* css/html.css:
(input[type="file"]::-webkit-file-upload-button):
Specify font-size:inherit explicitly.

LayoutTests:

* fast/forms/file/file-style-inheritance-expected.txt: Added.
* fast/forms/file/file-style-inheritance.html: Added.
