There are needs to use lambda expression and composite PrimExpr in meta schedule traces. For example:

sch.layout_transform(block, buffer_index, lambda x, y: x ^ y, y)
sch....(loop, ..., a + b)

The way we enable this is to actually convert them into an Array which is serializable:

lambda x, y: x ^ y, y => ["lambda", /*inputs = */[x, y], /*outputs = */[x ^ y, y]]
a + b => ["prim_expr", /*inputs = */[a, b], /*outputs = */a + b]

Per discussion with @vinx13
