perl.h: define PERL_BITFIELD8/16/32 as U8/U16/U32

After consultation with xenu we decided that defining both sets exactly the same
as U8/U16/U32 makes the most sense.

These defines were added in 654eccd594bfe8deab367b0f4cdda726a7796ff3 and the discussion
for why is here: https://www.nntp.perl.org/group/perl.perl5.porters/2008/01/msg133754.html

Short summary: Activestate added these defines so that XS code compiled with gcc on windows
could be used with a perl compiled with VC on windows, and vice-versa. Read the thread
for more details.

This patch does NOT remove the duplicate definition in win32/win32.h, I
don't feel comfortable doing that without being able to check the build,
so I will leave it to someone who has VC to test.
