Subject: HIL: replace build.flags_on with named build variants (#3687)

* test/hil: replace build.flags_on with named variant schema

Boards declare build variants as `variant: [{name, flags}]` instead of
`build.flags_on`. The variant `name` is the build dir (cmake-build-<name>) and
the HIL report row; `flags` is the raw CFLAGS string (-D...=1) injected via
CFLAGS_CLI. No `variant` => a single build named after the board.

- build.py: --build-name <name> (dir) + --cflag=<token> (raw CFLAGS, repeatable,
  =form survives the matrix's shell word-splitting); drop -f1/CFLAGS wrapping.
- hil_ci_set_matrix.py: emit one build arg per variant.
- hil_test.py: iterate variants; report row + build dir = variant name.
- hil_ci.sh: copy all cmake-build-<board>* dirs for -b runs.
- get_deps.py: accept (ignore) --build-name/--cflag from matrix args.
- tinyusb.json: migrate all 6 flags_on boards to variant.

* board_test: park CI build with busy spin instead of wfe
