Changes

* "nnjitpluginSetupDiagnostics", this is optional. When successful and the funcptr is valid, this is called with w0=1 and x1 = {ptr to a funcptr on stack, the func for this is a duplicate of the one referenced above}.

* "nnjitpluginSetupDiagnostics", this is optional. When successful and the funcptr is valid, this is called with w0=1 and x1 = {ptr to a funcptr on stack, the func for this is a duplicate of the one referenced above}.

* "nnjitpluginConfigure", error is handled on failure. When [[Settings_services#GetDebugModeFlag|GetDebugModeFlag]] returns true, the symbol funcptr is called with x0 = {ptr where 2 output u32s are located}, and then the two output u32s are loaded (that data on stack is cleared prior to calling the funcptr). Otherwise when false, it's called with x0=0 and the fields which would contain the output u32s are cleared to 0. These fields are "nn::jit::MemorySecurityMode".

* "nnjitpluginConfigure", error is handled on failure. When [[Settings_services#GetDebugModeFlag|GetDebugModeFlag]] returns true, the symbol funcptr is called with x0 = {ptr where 2 output u32s are located}, and then the two output u32s are loaded (that data on stack is cleared prior to calling the funcptr). Otherwise when false, it's called with x0=0 and the fields which would contain the output u32s are cleared to 0. These fields are "nn::jit::MemorySecurityMode".

* {calls a vtable funcptr, and handles error on failure}

* The symbol for "nnjitpluginControl" is loaded, with the funcptr copied into state. On success, the same is done with "nnjitpluginGenerateCode". If either of these fail, error handling will run.

* TransferMemory init is done here. An ASLR'd address for the TransferMemory mapped-address is determined, which will then be reused for all later mappings.

* CodeMemory init func-calling is done for both regions, where w1={first output from "nnjitpluginConfigure" above}. Likewise with the TransferMemory, with w1={second output from "nnjitpluginConfigure" above}.
