Merge bitcoin/bitcoin#30048: crypto: add `NUMS_H` const

Broken out from #28122

[BIP341](https://github.com/bitcoin/bips/blob/master/bip-0341.mediawiki#constructing-and-spending-taproot-outputs) defines a NUMS point `H` as *H = lift_x(0x50929b74c1a04954b78b4b6035e97a5e078a5a0f28ec96d547bfee9ace803ac0)* which is [constructed](https://github.com/ElementsProject/secp256k1-zkp/blob/11af7015de624b010424273be3d91f117f172c82/src/modules/rangeproof/main_impl.h#L16) by taking the hash of the standard uncompressed encoding of the [secp256k1](https://www.secg.org/sec2-v2.pdf) base point G as X coordinate."
Add this as a constant so it can be used in our codebase. My primary motivation is BIP352 specifies a special case for when taproot spends use `H` as the internal key, but outside of BIP352 it seems generally useful to have `H` in the codebase, for testing or other use cases.
