Another single-function file goes away.

The latter was used for EC_GROUP_new_curve_GF2m() and is now pointless.

Currently, if compiled without OPENSSL_BN_ASM_MONT,
EC_GROUP_new_curve_GFp() tries to use EC_GFp_nist_method(), falling back to
EC_GFp_mont_method() if it is not a NIST curve (if OPENSSL_BN_ASM_MONT is
defined we use EC_GFp_mont_method() unconditionally).
Now that we have a reasonable non-assembly Montgomery implementation, the
performance of EC_GFp_nist_method() is either similar or slower than
EC_GFp_mont_method() (the exception being P-521, however if you're using
that you're not doing it for performance reasons anyway).
The EC_GFp_nist_method() uses rather scary BN NIST code (which would
probably already be removed, if not for the BN and EC public APIs), it uses
code paths that are currently less constant time, and there is additional
overhead in checking to see if the curve is actually supported.
Stop trying to use EC_GFp_nist_method() and unconditionally use
EC_GFp_mont_method() in all cases. While here, factor out the common
setup code and call it from both EC_GROUP_new_curve_GFp() and
EC_GROUP_new_curve_GF2m().

Libcrypto currently has a mess of *_lcl.h, *_locl.h, and *_local.h names
used for internal headers. Move all these headers we inherited from
OpenSSL to *_local.h, reserving the name *_internal.h for our own code.
Similarly, move dtls_locl.h and ssl_locl.h to dtls_local and ssl_local.h.
constant_time_locl.h is moved to constant_time.h since it's special.
Adjust all .c files in libcrypto, libssl and regress.
The diff is mechanical with the exception of tls13_quic.c, where
#include <ssl_locl.h> was fixed manually.
discussed with jsing,

There are numerous functions in ec/ that exist with _GF2m and _GFp
variants for no good reason. The code of both variants is the same.
The EC_METHODs contain a pointer to the appropriate version. This
commit hides the _GF2m and _GFp variants from internal use and
provides versions that work for both curve types. These will be made
public in an upcoming library bump.
Similar to part of OpenSSL commit 8e3cced75fb5fee5da59ebef9605d403a999391b

an OPENSSL_NO_* define. This avoids relying on something else pulling it
in for us, plus it fixes several cases where the #ifndef OPENSSL_NO_XYZ is
never going to do anything, since OPENSSL_NO_XYZ will never defined, due
to the fact that opensslconf.h has not been included.
This also includes some miscellaneous sorting/tidying of headers.
