FTL: Extend enum utilities imported from IF

Generalize compile-time and run-time lookup of enumerator names by
recognizing ftl_first and ftl_last to customize the range.

Add enum_range<E>() for iteration using range-based `for` loop.

Bug: 185536303
Test: Check assembly for small LUT in .rodata, and unrolled loops.
Test: ftl_test, libinput_tests, inputflinger_tests
Test: m libinputflinger
