Support renamed SoftFloat types

[huangminghuang]

Summary

• Update sys-vm's SoftFloat integration to use the canonical softfloat32_t and softfloat64_t type names.
• Point the local Wire vcpkg registry config at the registry commit that contains softfloat@3.0.0#1.
• Bump the CMake package version to 1.1.1 to match the registry port version consuming this change.

What changed

• Renamed legacy SoftFloat carrier types in include/sysio/vm/softfloat.hpp and the x86_64 softfloat glue.
• Kept the non-SoftFloat x86_64 fallback aliases, but renamed them to the new canonical names so templated call sites stay uniform.
• Added the registry reference pin alongside the baseline so standalone eos-vm builds resolve the fixed SoftFloat port.

Why

softfloat@3.0.0#1 exports SOFTFLOAT_DISABLE_LEGACY_TYPE_ALIASES, so consumers can no longer rely on float32_t and float64_t. This lets sys-vm build against the fixed SoftFloat package used by the macOS arm64 Wire Sysio dependency update.
