Sema: mark pointers to inline functions as comptime-only

This is supposed to be the case, similar to how pointers to generic
functions are comptime-only (several pieces of logic already assumed
this). These types being considered runtime was causing `dbg_var_val`
AIR instructions to be wrongly emitted for such values, causing codegen
backends to create a runtime reference to the inline function, which (at
least on the LLVM backend) triggers an error.
