lua on f407 (#2646)

* lua on f4

* move perf trace to efifeatures

* check that it's defined

* cypress and kinetis

* it would help to define the correct thing

* disable buffer if not used

* we can work with 2k

* turn off ramdisk on mre qc

* wow strncpy is useless for truncated strings

* turn off for bootloader

* lto bootloader
