MdeModulePkg/Database: Fix incorrect calculation of baseline in FontPackage
When adding font package, there exists the case that only have the
EFI_HII_GIBT_GLYPH_DEFAULT or EFI_HII_GIBT_GLYPHS_DEFAULT glyph block
and use the default cell info in font package fixed header. In this
case, we can't get the correct baseline now. This patch is to fix this
issue by recalculating the baseline when the glyph block type is
EFI_HII_GIBT_GLYPH_DEFAULT or EFI_HII_GIBT_GLYPHS_DEFAULT.
