qt5: qtbase: Upgrade Double-Conversion

Backport the Double-Conversion upgrade from the dev branch
(https://codereview.qt-project.org/#/c/227718/) to the current release.
This fixes the RISC-V compile of QTBase.

Subject: [PATCH] Upgrade double-conversion to v3.0.0
This fixes their issue #41, a potential undefined behavior.
We preserve the locally added "__ghs" clause as well as the _M_ARM_FP
clause necessary for winrt in utils.h.
[ChangeLog][Third-Party Code] double-conversion got updated to upstream
version 3.0.0.
Task-number: QTBUG-66561
Change-Id: Id79125bdeeaebb61dca2e2885d3370accce9030c
Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
