Subject: [PATCH] build: make target microarchitecture configurable via vcpkg
 triplet

Rebased cleanly onto current main: this branch was previously based on
the stale master branch instead of main, and a later attempt to
resync tangled the branch with unrelated master-only history (a
license-text change, changelog/aspell-dictionary updates from real
upstream commits, none of which belong on this feature). Rebuilt as a
single clean commit containing just the arch-baseline wiring, on top
of current main.

Add ARCH_TRIPLET/ARCH_MARCH_FLAGS build args (default x64-linux-v2) to
build/docker-bake.hcl, build/linux/docker-bake.hcl, and
build/linux/build.sh, matching the overlay triplets and Dockerfile
wiring in the core and desktop-apps submodules (also rebuilt cleanly
onto their current main branches), so a baseline x86-64 build can be
produced by anyone who needs it without maintaining a second official
toolchain.
