Subject: [PATCH] GCC: make base::FilePath move assignment operator noexcept
The move assignment operator in PaintPreviewClient::PaintPreviewData is
noexcept. Because this class has a member of type base::FilePath, the
move assignment operator of base::FilePath must be noexcept too.
Otherwise GCC fails like this:
../../components/paint_preview/browser/paint_preview_client.cc:107:1:
error: function 'paint_preview::PaintPreviewClient::PaintPreviewData&
paint_preview::PaintPreviewClient::PaintPreviewData::operator=
(paint_preview::PaintPreviewClient::PaintPreviewData&&)' defaulted on
its redeclaration with an exception-specification that differs from
the implicit exception-specification ''
107 | PaintPreviewClient::PaintPreviewData::operator=(
