TVM instructions: SECP256K1_XONLY_PUBKEY_TWEAK_ADD, SETCONTCTRMANY(X) (#1404)

Browse source 
* TVM instructions: SECP256K1_XONLY_PUBKEY_TWEAK_ADD, SETCONTCTRMANY(X)

* Add tests for xonly_pubkey_tweak_add

* added secp256k1 as submodule, since we need extrakeys feature of secp256k1

* cleanup

* add ton_crypto_core secp256k1 dependency

* adjust Dockerfile, android and wasm builds

* adjust nix build

* test windows build with SECP256K1_ENABLE_MODULE_EXTRAKEYS

* test windows build with SECP256K1_ENABLE_MODULE_EXTRAKEYS

* adjust android build

* adjust emscripten build

* adjust emscripten build

* try macos-13

* emscripten build adjustments

* windows build adjustments

* final corrections

## Version 9
### New TVM instructions
- `SECP256K1_XONLY_PUBKEY_TWEAK_ADD` (`key tweak - 0 or f x y -1`) - performs [`secp256k1_xonly_pubkey_tweak_add`](https://github.com/bitcoin-core/secp256k1/blob/master/include/secp256k1_extrakeys.h#L120).
`key` and `tweak` are 256-bit unsigned integers. 65-byte public key is returned as `uint8 f`, `uint256 x, y` (as in `ECRECOVER`). Gas cost: `1276`.
- `mask SETCONTCTRMANY` (`cont - cont'`) - takes continuation, performs the equivalent of `c[i] PUSHCTR SWAP c[i] SETCONTCNR` for each `i` that is set in `mask` (mask is in `0..255`).
- `SETCONTCTRMANYX` (`cont mask - cont'`) - same as `SETCONTCTRMANY`, but takes `mask` from stack.
### Other changes
- Fix `RAWRESERVE` action with flag `4` (use original balance of the account) by explicitly setting `original_balance` to `balance - msg_balance_remaining`.
- Previously it did not work if storage fee was greater than the original balance.
- Jumps to nested continuations of depth more than 8 consume 1 gas for eact subsequent continuation (this does not affect most of TVM code).

/* This module provides an implementation of ElligatorSwift as well as a
* version of x-only ECDH using it (including compatibility with BIP324).
*
* ElligatorSwift is described in https://eprint.iacr.org/2022/759 by
* Chavez-Saab, Rodriguez-Henriquez, and Tibouchi. It permits encoding
* uniformly chosen public keys as 64-byte arrays which are indistinguishable
* from uniformly random arrays.
*
* Let f be the function from pairs of field elements to point X coordinates,
* defined as follows (all operations modulo p = 2^256 - 2^32 - 977)
* f(u,t):
* - Let C = 0xa2d2ba93507f1df233770c2a797962cc61f6d15da14ecd47d8d27ae1cd5f852,
* a square root of -3.
* - If u=0, set u=1 instead.
* - If t=0, set t=1 instead.
* - If u^3 + t^2 + 7 = 0, multiply t by 2.
* - Let X = (u^3 + 7 - t^2) / (2 * t)
* - Let Y = (X + t) / (C * u)
* - Return the first in [u + 4 * Y^2, (-X/Y - u) / 2, (X/Y - u) / 2] that is an
* X coordinate on the curve (at least one of them is, for any u and t).
*
* Then an ElligatorSwift encoding of x consists of the 32-byte big-endian
* encodings of field elements u and t concatenated, where f(u,t) = x.
* The encoding algorithm is described in the paper, and effectively picks a
* uniformly random pair (u,t) among those which encode x.
*
* If the Y coordinate is relevant, it is given the same parity as t.
*
* Changes w.r.t. the paper:
* - The u=0, t=0, and u^3+t^2+7=0 conditions result in decoding to the point
* at infinity in the paper. Here they are remapped to finite points.
* - The paper uses an additional encoding bit for the parity of y. Here the
* parity of t is used (negating t does not affect the decoded x coordinate,
* so this is possible).
*
* For mathematical background about the scheme, see the doc/ellswift.md file.

* 1. The nonrepeating_cnt argument must be a counter value that never repeats,
* i.e., you must never call `secp256k1_musig_nonce_gen_counter` twice with

* that if the same keypair is used with `secp256k1_musig_nonce_gen_counter`
* on multiple devices, none of the devices should have the same counter
* value as any other device.
* 2. If the seckey, message or aggregate public key cache is already available

/** Create a Schnorr signature with a more flexible API.
*
* Same arguments as secp256k1_schnorrsig_sign except that it allows signing
* variable length messages and accepts a pointer to an extraparams object that
* allows customizing signing by passing additional arguments.
*
* Equivalent to secp256k1_schnorrsig_sign32(..., aux_rand32) if msglen is 32
* and extraparams is initialized as follows:
* ```
* secp256k1_schnorrsig_extraparams extraparams = SECP256K1_SCHNORRSIG_EXTRAPARAMS_INIT;
* extraparams.ndata = (unsigned char*)aux_rand32;
* ```
*
* Returns 1 on success, 0 on failure.
* Args: ctx: pointer to a context object (not secp256k1_context_static).
* Out: sig64: pointer to a 64-byte array to store the serialized signature.
* In: msg: the message being signed. Can only be NULL if msglen is 0.
* msglen: length of the message.
* keypair: pointer to an initialized keypair.
* extraparams: pointer to an extraparams object (can be NULL).
