[WTF] Fix performance when creating Vectors from different constness
https://bugs.webkit.org/show_bug.cgi?id=299008
Reviewed by Chris Dumez.
For example, when you try to create a Vector<uint8_t> from a span<const
uint8_t>, templates will consider both types
different and even when you pass true to the template, the second
VectorCopier::uninitializedCopy function will be used
and will defer to the slow version.
My use case was in MSE, creating a SharedBuffer implies creating a
FragmentedSharedBuffer and then a DataSegment that
implicitly creates a Vector<uint8_t> from a span<const uint8_t>. If you're
copying 2.5MB, time is reduced to 33% of the
initial one.
