build: Introduce SECP256K1_STATIC macro for Windows users 
It is a non-Libtool-specific way to explicitly specify the user's
intention to consume a static `libseck256k1`.

This change allows to get rid of MSVC linker warnings LNK4217 and
LNK4286. Also, it makes possible to merge the `SECP256K1_API` and
`SECP256K1_API_VAR` into one.

c47917bbd6 Add ellswift module implementing ElligatorSwift 
The scheme implemented is described below, and largely follows the paper
"SwiftEC: Shallue–van de Woestijne Indifferentiable Function To Elliptic Curves",
by Chavez-Saab, Rodriguez-Henriquez, and Tibouchi
(https://eprint.iacr.org/2022/759).

A new 64-byte public key format is introduced, with the property that *every*
64-byte array is an encoding for a non-infinite curve point. Each curve point
has roughly 2^256 distinct encodings. This permits disguising public keys as
uniformly random bytes.

The new API functions:
* secp256k1_ellswift_encode: convert a normal public key to an ellswift 64-byte
  public key, using additional entropy to pick among the many possible
  encodings.
* secp256k1_ellswift_decode: convert an ellswift 64-byte public key to a normal
  public key.
* secp256k1_ellswift_create: a faster and safer equivalent to calling
  secp256k1_ec_pubkey_create + secp256k1_ellswift_encode.
* secp256k1_ellswift_xdh: x-only ECDH directly on ellswift 64-byte public keys,
  where the key encodings are fed to the hash function.

The scheme itself is documented in secp256k1_ellswift.h.

8c7e0fc1de build: Add -Wreserved-identifier supported by clang 
This warns on certain identifiers reserved by the C standard, namely
 * identifiers that begin with an underscore followed by an uppercase
   letter, and
 * identifiers in the global namespace that begin with an underscore.

We had used such identifiers in the past for macros in include guards,
and we should make sure that we don't reintroduce such identifiers
going forward.

Note that C reserves more identifiers for "future library directions",
e.g., identifiers that begin with "str" followed by a lowercase letter.
But even the C standards committee has decided that this is somewhat
silly and adopted a proposal [1] for C23 that removes the restriction
that programs using these identifiers have UB. Instead, these
identifiers are now "potentially reserved", which is not a normative
restriction but simply an informative warning that the identifiers
may become fully reserved in the future.
