BaseTools/Expression: Use 2nd passes on PCD values
Use 2 passes when evaluating PCD values to discover
all the LABEL() operators and compute the byte offset
of each LABEL(). The 2nd pass then has the information
to replace the OFFSET_OF() operator with the computed
byte offset. The 2 passes allows OFFSET_OF() to be used
before a LABEL() is declared.
