[ion] 24408: - Implement ExpInitNls to initialize the NLS Section using the new semantics recently implemented. Works pretty much like the previous code in rtl/nls.c except it uses the new variable names as well as maps a view of the NLS Table into the system process.c - Delete rtl/nls.c and all the associated deprecated code. - Do MmInit1 and SharedUserData stuff *after* initializing the initial thread, to avoid an ASSERT during bootup.

Log:
- Implement ExpInitNls to initialize the NLS Section using the new semantics recently
implemented. Works pretty much like the previous code in rtl/nls.c except it uses the new
variable names as well as maps a view of the NLS Table into the system process.c
- Delete rtl/nls.c and all the associated deprecated code.
- Do MmInit1 and SharedUserData stuff *after* initializing the initial thread, to avoid an
ASSERT during bootup.
