--output_groups=Foo.lef is wrong for mocked artifacts

[oharboe]

Below the unmocked .lef file instead of the mocked .lef file is in the--output_group=lb_32x128.lef of lb_32x128_generate_abstract

orfs_flow(
    name = "lb_32x128",
    arguments = LB_ARGS,
    mock_area = 0.5,
    stage_sources = LB_STAGE_SOURCES,
    verilog_files = LB_VERILOG_FILES,
)

@jeffng-or @maliberty The wrong area seem to have been used for the mocked srams in megaboom compared to our intentions...

Mostly the macros are 3x too large (mock_area=0.33) on the side, so ~10x too large area compared to our intentions. Though the caches have been underestimated in size. Looks like data cache by 3x on the size and instruction cache by 1.2x on the size.
