[TTI][AMDGPU] Allow targets to adjust `LastCallToStaticBonus` via `getInliningLastCallToStaticBonus` (#111311)
Currently we will not be able to inline a large function even if it only
has one live use because the inline cost is still very high after
applying `LastCallToStaticBonus`, which is a constant. This could
significantly impact the performance because CSR spill is very
expensive.
This PR adds a new function `getInliningLastCallToStaticBonus` to TTI to
allow targets to customize this value.
Fixes SWDEV-471398.
