[Feat] Support fast fail option for tcl test cases

[arthurkiller]

Hi, new here in valkey community.

This PR added a new option for tcl test case which will fail fast once any test cases fail. This can be useful while running redis CI pipeline, and you want to accelerate the CI pipeline.

Appreciate all the things you guys have done, hope can contribute to this project.

usage for example

./runtest --single unit/type/hash --fastfail

[ok]: HSET/HLEN - Small hash creation (2 ms)
[ok]: Is the small hash encoded with a listpack? (0 ms)
[ok]: HRANDFIELD - listpack (8 ms)
[ok]: HRANDFIELD - hashtable (7 ms)
Test error (last server port:21113, log:./tests/tmp/server.3935664.1/stdout), test will exit now
[err]: HRANDFIELD with RESP3 in tests/unit/type/hash.tcl
Expected '3' to be equal to '2333' (context: type eval line 8 cmd {assert_equal [llength $res] 2333} proc ::test)
(Fastfail: test will exit now)
