chore(perf): Optimize the Copy method of the Context struct (#3859)

* Optimize the Copy method of the Context struct: using 'make' to initialize the map('cp.Keys') with a length of 'c.Keys'; avoiding repeatedly assiging the 'params' to 'context'.

* Using temporary variables to save c.Keys and c.Params to prevent them from changing during the copying process.
