Maybe we can put these code into uspace.rs.

Description
This pull request introduces significant updates across multiple architectures to improve context management, particularly around thread-local storage (TLS) and syscall argument handling. The changes include adding getter and setter methods for syscall arguments, instruction pointers, stack pointers, and TLS areas, as well as refactoring context-switching logic to better support kernel-space TLS.
Additional Notes
This is a step towards gradually merging downstream oscamp/arceos into the main branch.
