Upstream Go CL https://go.dev/cl/652276 removes an unused field from
runtime.gobuf. This CL prepares for this change.
This CL also simplifies the build constraints in the hosttid files:
- Remove legacy '// +build' constraint syntax
- Remove explicit GOARCH matching. The GOARCH is in the filename

For all trivial and zero frame-sized functions, we now require an explicit
NOFRAME annotation as the heuristic has changed. See go.dev/cl/466316.
Most of these functions do not *require* NOFRAME, but this change encodes
the existing behavior in order to avoid accidental bugs or regressions.

This allows fact information to be validated in the underlying source files,
but requires us to explicitly maintain this in appropriate version-tagged, and
architecture-tagged files. This is more explicit and safer.
This mechanism uses a special regular expression for matching a +checkconst
stanza to validate constant values, sizes and offsets. This applies to both Go
source files and assembly files.

"procid" implies "process ID", "processor (CPU?) ID", or "`runtime.p.id`". It
is none of these things. Instead, `procid.Current()` returns the caller's host
thread ID; almost every caller relies on this property. Rename the package
accordingly.
Nit: Replace "system thread identifier" with "host thread ID". "System" is
needlessly vague in a setting where many callers will also have an unrelated
application thread ID, and "identifier" is a guess at what is abbreviated by
"thread ID" - but cf. gettid(2), "NAME: gettid - get thread identification".
