vcl: remove OutputDevice's GetDevFontSizeCount() and GetDevFontSize()

The OutputDevice::GetDevFontSize() function is only used for
non-scalable (bitmap) fonts. We have stopped supporting bitmap fonts
since LO 5.3, see tdf#103514: Support for bitmap-only fonts on Windows
has been removed (Khaled Hosny)

I found the following when removing PhysicalFontFace::SetBitmapSize():

1. as mnHeight and mnWidth and not set by anyone, I realized I could
remove them, which meant removing GetHeight() and GetWidth()

2. PhysicalFontFamily::GetFontHeights() populates heights from the
collection of font faces into a sorted vector of font heights taken
from PhysicalFontFace. As this no longer exists this function
serves no purpose, it has been removed.

3. PhysicalFontFamily::GetDeviceFontSizeList() calls upon
PhysicalFontFace::GetFontHeights(). This function takes this sorted
list of font heights, and then populates and returns a new list of
sizes (or rather, heights). As the heights aren't available any
more, this function is also unneeded, so it has been removed.

4. OutputDevice::GetDevFontSizeCount() calls upon
PhysicalFontFamily::GetDeviceFontSizeList(). This function has the
side effect of initializing the list of fonts.

5. When I checked what calls on GetDevFontSizeCount(), there is only
one caller - FontList::GetSizeAry() in svtools. The function returns
a standard font size list if the family name is empty, or there are
no font sizes (via OutputDevice::GetDevFontSizeCount()). As this
will *always* be empty (see chain above) then this function just
needs to always return a standard font size list.

Thus OutputDevice::GetDevFontSizeCount() and GetFontSizeList() are
no longer called upon by anything, so they can be removed.

6. svtool's FontList::GetSizeAry() no longer uses the FontMetric
parameter, so this has been removed from the function signature, and
cleanup done of the function that calls upon it in svtools,
framework, editeng, and desktop. A number of variables that were no
longer used due to this change were also removed.

7. This change removed the need for the mpSizeAry unique_ptr in
FontList. ImplFontListFontMetric::GetDevice() and mpDevice could
also be removed as it was no longer used anywhere.

8. After simplifying GetSizeAry(), it turns out it was the same as
GetStdSizeAry(), so removed FontList::GetSizeAry() and used
FontList::GetStdSizeAry() in its place.

9. Changing to use GetStdSizeAry() revealed that FontSizeBox::Fill()
no longer used the pFontMetric paramter, so this was removed, and
call sites updated.

10. Due to change to Fill():

a. SvxFontSizeBox_Base::UpdateFont() no longer uses the
const css::awt::FontDescriptor& rCurrentFont parameter, so
removed this. This also removed the member variable
m_aCurrentFont

b. SvxCharNamePage::FillSizeBox_Impl() had a number of newly
unused variables removed.

c. SwStdFontTabPage::Reset() and
SwStdFontTabPage::LoseFocusHdl() had a number of newly unused
variables removed.
