Jit: Use LazyMemoryRegion-backed bit sets

JitCache has been using a class called ValidBlockBitSet. This commit
replaces it with a new class called LazyMemoryRegionBitSet, which works
similarly but is backed by a LazyMemoryRegion, letting us skip
allocating memory for parts of the bit set that correspond to emulated
memory regions where the game isn't storing any code. I have also added
optimized functions for setting or clearing long runs of bits.

Additionally, this commit replaces JitBase's three std::unordered_sets
that are keeping track of instructions with LazyMemoryRegionBitSets.
Here the benefit is more speed than memory usage. This improves NBA Live
2005's menu performance by 1% or so in SuperSamus's testing.
