This adds the experimental support of the file system compilation cache.
Notably, experimental.WithCompilationCacheDirName allows users to configure
where the compiler writes the cache into.
Versioning/validation of binary compatibility has been done via the release tag
(which will be created from the end of this month). More specifically, the cache
file starts with a header with the hardcoded wazero version.

FreeBSD was disabled due to lack of testing. This works around the
compilation problems. Note: We can't currently test arm64 automatically!
Notes:
* GitHub Actions doesn’t support FreeBSD, and may never.
* We could use Travis to run FreeBSD, but it would split our CI config.
* Using Vagrant directly is easier to debug than vmactions/freebsd-vm.
* GitHub Actions only supports virtualization on MacOS.
* GitHub Actions removed vagrant from the image starting with macos-11.
* Since VirtualBox doesn't work on arm64, freebsd/arm64 is untestabl

This removes the embedding of pointers of jump tables (uintptr of []byte)
used by BrTable operations. That is the last usage of unsafe.Pointer in
compiler implementations.
Alternatively, we treat jump tables as asm.StaticConst and emit them
into the constPool already implemented and used by various places.
Notably, now the native code compiled by compilers can be reusable
across multiple processes, meaning that they are independent of
any runtime pointers.

This completes the implementation of arm64 backend for SIMD instructions.
Notably, now the arm64 compiler passes 100% of WebAssemby 2.0 draft
specification tests.
Combined with the completion of the interpreter and amd64 backend (#624),
this finally resolves#484. Therefore, this also documents that wazero is
100% compatible with WebAssembly 1.0 and 2.0.

This completes the implementation of SIMD proposal for both
the interpreter and compiler(amd64).
This also fixes#210 by adding the complete documentation
over all the wazeroir operations.

This moves the platform-specific runtime code (currently only used by
the compiler) into its own package. Specifically, this moves the mmap
logic, and in doing so makes it easier to test, for example new
operating systems.
This also backfills missing RATIONALE about x/sys and hints at a future
possibility to allow a plugin. However, the next step is to get FreeBSD
working natively on the compiler without any additional dependencies.

This notably changes NewRuntimeJIT to NewRuntimeCompiler as well renames
packages from jit to compiler.
This clarifies the implementation is AOT, not JIT, at least when
clarified to where it occurs (Runtime.CompileModule). In doing so, we
reduce any concern that compilation will happen during function
execution. We also free ourselves to create a JIT option without
confusion in the future via CompileConfig or otherwise.
