Follow the <if expr="use_titlecase"> pattern of other similar strings.

Tested, and I found this way works.

But I am curious, how is the string selection determined? Namely, How does the
system know I need "Share Your Screen", not "Share your screen" as the window
title.

Each platform sets the use_titlecase build flag value, and that determines which
string is included in the string resource pak files built/shipped/used. Take a
look at use_titlecase mentions build/common.gypi, tools/grit/grit_rule.gni, etc.
if you're interested in the nitty-gritty.
