devel/extra-cmake-modules: Use buildlink3.mk, not TOOL_DEPENDS.

This one is borderline: should it be BUILD_DEPENDS or TOOL_DEPENDS?
It doesn't appear to vary depending on the build environment, so it
doesn't meaningfully describe the cross-builder vs the target system.
It is used only at build-time, but it doesn't have any native
executables -- they're just source code cmake scripts.

For now, it is convenient to use a buildlink3.mk file because this
enables us to explicitly expose only files under share/ECM/ -- and
not other random files installed in the prefix -- via buildlink3 to
keep dependent package builds clean.  Eventually we should have the
same mechanism for TOOL_DEPENDS but that day has not yet come.

This change creates a new use of BUILDLINK_DEPMETHOD build for
extra-cmake-modules, which is a priori risky.  Fortunately,
extra-cmake-modules has no libraries, so this is unlikely to cause
trouble.

Changelog:
Some optimizations.
Update documents and demos.

Log message:
Mass-change BUILD_DEPENDS to TOOL_DEPENDS outside mk/.

Almost all uses, if not all of them, are wrong, according to the
semantics of BUILD_DEPENDS (packages built for target available for
use _by_ tools at build-time) and TOOL_DEPEPNDS (packages built for
host available for use _as_ tools at build-time).

No change to BUILD_DEPENDS as used correctly inside buildlink3.

Log message:
*: Re-apply SunOS linker argument removals.

These are currently duplicated in mk/platform/SunOS.mk but the generic
removals will be removed soon in favour of per-package removals, due to
flags getting leaked into installed files.

x11/xcb-imdkit: import xcb-imdkit-1.0.2

xcb-imdkit is an implementation of xim protocol in xcb, comparing
with the implementation of IMDkit with Xlib, and xim inside Xlib,
it has less memory foot print, better performance, and safer on
malformed client.
