Motivation: In debug builds, `DebugOnlyTraceFlag`s are hard-coded to be
disabled. This results in unreachable code paths that the compiler can
detect, which prevent us from enabling `-Wunreachable-code-aggressive`
on the builds.
This work aims to reduce the number of places that switch on
`trace_flag.enabled`.

* Implement type safety for TLS
This is mostly free when compiler support is available, but requires
careful templating when implemented using pthread.
Significantly slimmed the tls.h interface; it now only defines the "TLS
keyword" for each supported compiler, delegating enforcement of correct
usage (i.e. must be static) to the compiler itself.
Implemented implicit conversion for the pthread wrapper so it can be
used (mostly) the same as native support. Notable exception to this is
that static_cast<void*> is needed when printing a pointer stored in TLS
as %p.
* Use GPR_THREAD_LOCAL macros consistently
* Buffer HPACK parsing until the end of a header boundary
HTTP2 headers are sent in (potentially) many frames, but all must be
sent sequentially with no traffic intervening.
This was not clear when I wrote the HPACK parser, and still indeed quite
contentious on the HTTP2 mailing lists.
Now that matter is well settled (years ago!) take advantage of the fact
by delaying parsing until all bytes are available.
A future change will leverage this to avoid having to store and verify
partial parse state, completely eliminating indirect calls within the
parser.

Most instances were already explicit through comments, so it's clear
that the author cared about being explicit; use the compiler to ensure
this is always the case.

A simple bitset type -- to replace `std::bitset` usage in #26698 and #26254
`std::bitset` uses at least 64 bits even to store two bits, and the usages I'm looking at would benefit from having something smaller in those circumstances
The XDS code incurs a significant binary size increase, and isn't
generally relevant/useful to builds of gRPC for mobile platforms.
Note that this makes it impossible to build the XDS for mobile platforms
(as opposed to turning XDS off by default but still allowing it to be
force-enabled via a config flag). We're going this route, because any
approach that turns the feature off by default on some platforms but
that still allows force-enabling it on those platforms ends up hitting
either bazel's limits (bazel doesn't support a select() statement where
multiple branches match), or ends up having to rely on the linker to
strip out unused code (by still including the srcs and deps
unconditionally, and using a preprocessor directive to remove symbol
references, which the linker can then remove), which we don't want to do
because relying on the linker makes it too easy to accidentally
re-introduce symbol references.

This code adds an iomgr implementation that's backed by an EventEngine. This uses the EventEngine API alone, and separate work will introduce an EventEngine prototype to plug into it.
See also drfloob#1: @nicolasnoble has a pull request against this branch, implementing the libuv-based EventEngine. One goal here is to implement the iomgr code such that it can be merged independently without affecting normal builds.
This implementation can be built using bazel build --cxxopt='-DGRPC_USE_EVENT_ENGINE' :all
Some shortcuts are being taken to get a working, testable version of the engine. EventEngines are not pluggable, for example.
