vte: upgrade 0.78.2 -> 0.80.3

0004-fast_float-Add-single-header-library-for-from_char-i.patch
and 0005-color-parser-Use-fast_float-implementation-for-from_.patch
patches dropped: upstream has adopted the changes, and oe-core also
provides now fastfloat, no need to vendor it with a patch.

0002-lib-Typo-fix.patch is dropped, because it was a backport, and
it is included in this release.
