build: fix config.mk parser and add missing BUILD.bazel files

Fix several issues preventing `bazelisk test //flow/designs/asap7/...`
from working:

Parser fixes (config_mk_parser.py):
- Add _tokenize_make_expr() to preserve $(...) nesting when splitting
  multi-value VERILOG_FILES (fixes wildcard resolution for ibex, cva6)
- Fix _dir_to_verilog_label() to preserve subdirectory paths instead
  of collapsing all to top-level :verilog label
- Fix _resolve_include_path() to find included files when repo rule
  runs from a different CWD (fixes mock-alu defaults.mk include)
- Skip tab-indented Make recipe lines (fixes mock-alu MOCK_ALU_WIDTH)

Bazel rule fixes (orfs.bzl):
- Add VERILOG_INCLUDE_DIRS directories as stage_data for synth so
  include files are available in the Bazel sandbox

New BUILD.bazel files:
- 3 missing design dirs: aes, ethmac_lvt, swerv_wrapper
- 21 cva6 src subdirectories for nested verilog/include files
- ibex, jpeg include directories

Disable orfs_design() for designs with pre-existing issues:
- cva6, minimal, mock-cpu, riscv32i, swerv_wrapper
