  To: sai.gowtham.ch, igt-dev

Following Changes are done in gem_exec_fence program.

1) Added __for_each_physical_engine .
2) moved subtests from static to dynamic

List of subtests that are modified:
1) basic-busy
2) basic-wait
3) basic-await
4) nb-await
5) keep-in-fence
6) parallel
7) busy-hang
8) wait-hang
9) await-hang
10) nb-await-hang
11) basic-busy-all
12) basic-wait-all
13) busy-hang-all
14) wait-hang-all

V1 -> V2

Corrected subtest name in fast-feedback.testlist from,
basic-busy-default --> basic-busy
basic-wait-default --> basic-wait
basi-await-deafult --> basic-await
nb-await-default --> nb-await
