drm/amd/display: fix cursor refactor fallout and sync UT headers

Browse source

[Why]
UT mirror headers still declared the old prototypes and hwss_gtest still
called the callback directly. Separately, the divide by
param.pixel_clk_khz used to sit after hubp401_cursor_set_position()'s
"curs_attr.address == 0" early return; hoisting the math into the
builder moved it ahead of that guard, so it now traps on streams with
no timing programmed.

[How]
Guard the dst_x_offset block with "if (param.pixel_clk_khz)"
Route the test through hwss_program_cursor_position().
Update dc_hwss_ut.h / dc_hwseq_ut.h and the BLS docs to the new signatures.
Move the pos/param declarations to the top of the loop body.
