This CL does the following:
- Add the ability for nested locks to have names.
- Give names to all current uses of nested locks in the codebase.
- Truncate `lockdep` debug stack traces to avoid the clutter from the
`lockdep` code itself
- Simplify `lockdep` to not longer require `classMap`.

Build constraints are now inferred from go:build directives rather than +build
directives. +build directives are still emitted in generated files as required
in Go 1.16 and earlier.
Note that go/build/constraint was added in Go 1.16, so gVisor now requires Go
1.16.

These are primarily simplification and lint mistakes. However, minor
fixes are also included and tests added where appropriate.

This requires several changes:
* Templates must preserve relevant tags.
* Pagetables templates are split into two targets, each preserving tags.
* The binary VDSO is similarly split into two targets, with some juggling.
* The top level tools/go_branch.sh now does a crossbuild of ARM64 as well,
and checks and merges the results of the two branches together.

Using the newer bazel rules necessitates a transition from proto1 to
proto2. In order to resolve the incompatibility between proto2 and
gogoproto, the cri runtimeoptions proto must be vendored.
Further, some of the semantics of bazel caching changed during the
transition. It is now necessary to:
- Ensure that :gopath depends only on pure library targets, as the
propagation of go_binary build attributes (pure, static) will
affected the generated files (though content remains the same,
there are conflicts with respect to the gopath).
- Update bazel.mk to include the possibility of binaries in the
bazel-out directory, as it will now put runsc and others there.
This required some refinements to the mechanism of extracting
paths, since some the existing regex resulted in false positives.
- Change nogo rules to prevent escape generation on binary targets.
For some reason, the newer version of bazel attempted to run the
nogo analysis on the binary targets, which fails due to the fact
that objdump does not work on the final binary. This must be due
to a change in the semantics of aspects in bazel3.

For some reason these tests were broken when run via the bazel docker
container. The mechanism used was a bit crazy (self-extracting bundle),
so convert them to use straight-forward starlark rules. This has the
added advantaged that they are now independent tests.

This change implements gap tracking in the segment set by adding additional
information in each node, and using that information to speed up gap finding
from a linear scan to a O(log(n)) walk of the tree.
This gap tracking is optional, and will default to off except for segment
instances that set gapTracking equal to 1 in their const lists.
