[PATCH i-g-t, v5 2/4] tests/kms_joiner_helper: Add igt_is_joiner_supported_by_source()

[Swati Sharma <swati2.sharma@intel.com>]

Add func() returning true/false if platform supports big/ultra
joiner and use corresponding func() in related binaries.

v2: -Moved func() to joiner_helper (Jeevan)
    -Use common func for ultra|big joiner (Ankit)
v3: -Rename param type to joiner_type (Ankit)
    -Fix ultra joiner condition logic (Karthik, Ankit)
