  MCAsmBackend,Hexagon: Remove MCRelaxableFragment from fixupNeedsRelaxationAdvanced

Among fixupNeedsRelaxationAdvanced (introduced by
https://reviews.llvm.org/D8217) targets, only Hexagon needs the
`MCRelaxableFragment` parameter (commit
86f218e7ec5d941b7785eaebcb8f4cad76db8a64) to get the instruction packet
(MCInst with sub-instruction operands).

As fixupNeedsRelaxationAdvanced follows mayNeedRelaxation, we can store
the MCInst in mayNeedRelaxation and eliminate the MCRelaxableFragment
parameter.

Follow-up to 7c83b7ef1796210451b839f4c58f2815f4aedfe5 that eliminates
the MCRelaxableFragment parameter from fixupNeedsRelaxation.
