Merge bitcoin/bitcoin#30120: Update libsecp256k1 subtree to current master
a057869aa3c42457570765966cb66accb2375b13 build: pass --with-ecmult-gen-kb=86 to secp256k1 (fanquake)
ca3d945dc66e177e8fa3e83c77236de89cc0072a Squashed 'src/secp256k1/' changes from d8311688bd..06bff6dec8 (fanquake)
Pull request description:
This includes changes from the 0.5.0 release: https://github.com/bitcoin-core/secp256k1/releases/tag/v0.5.0
> New function secp256k1_ec_pubkey_sort that sorts public keys using lexicographic (of compressed serialization) order.
> The implementation of the point multiplication algorithm used for signing and public key generation was changed, resulting in improved performance for those operations.
> The related configure option --ecmult-gen-precision was replaced with --ecmult-gen-kb (ECMULT_GEN_KB for CMake).
> This changes the supported precomputed table sizes for these operations. The new supported sizes are 2 KiB, 22 KiB, or 86 KiB (while the old supported sizes were 32 KiB, 64 KiB, or 512 KiB).

ACK a057869aa3c42457570765966cb66accb2375b13, I've got a zero diff with my local branch, which reproduces the subtree update, and `ecmult gen table size = 86 KiB` in the configure summary.
