btcec: convert package into go module, alias to dcrec In this commit, we turn the package into a new Go module (version 2), and then port over the current set of types and functions to mainly alias to the more optimized and maintained dcrec variant. Taking a look at the benchmarks, most operations other than normalization (which IIRC is a bit slower now due to constant time fixes) enjoy some nice speeds up: ``` benchcmp is deprecated in favor of benchstat: https://pkg.go.dev/golang.org/x/perf/cmd/benchstat benchmark old ns/op new ns/op delta BenchmarkAddJacobian-8 464 328 -29.20% BenchmarkAddJacobianNotZOne-8 1138 372 -67.27% BenchmarkScalarBaseMult-8 47336 31531 -33.39% BenchmarkScalarBaseMultLarge-8 42465 32057 -24.51% BenchmarkScalarMult-8 123355 117579 -4.68% BenchmarkNAF-8 582 168 -71.12% BenchmarkSigVerify-8 175414 120794 -31.14% BenchmarkFieldNormalize-8 23.8 24.4 +2.39% BenchmarkParseCompressedPubKey-8 24282 10907 -55.08% ```

schnorr/musig2: add native support for taproot output key tweaking In this commit, we add a series of new options and methods to make it easier to use the package in the context of a taproot output that commits to a script root or some other value. Before this series of changes, the API was hard to use in this context as the taproot tweak actually includes the internal public key, which in this case is the aggregated public key. So you actually needed to call that API w/o the tweak, get that, then recompute the tweak itself. To make things easier in the taproot context, we've added a series of new options that'll return the aggregated key before any tweaks (to be used as the internal key), and also handle computing the BIP 341 tweak value for the caller.

btcec/v2: create new ecdsa package In this commit, we create a new package to house the ECDSA-specific logic in the new `btcec/v2` pacakge. Thsi c hange is meant to mirror the structure of the `dcrec` package, as we'll soon slot in our own custom BIP-340 implementation.
