ArmPkg: ensure DebugAgentVectorTable is 2K-aligned 

We force alignment to 2K after generating the DebugAgentVectorTable
symbol, and hence DebugAgentVectorTable itself may not be 2K-aligned,
and table entries may not be at the correct offset from the
DebugAgentVectorTable base address.

Fix this by forcing alignment before generating the
DebugAgentVectorTable symbol.
