Code style fixes and nits on the HLE project (#355)
* Some style fixes and nits on ITimeZoneService * Remove some unneeded usings * Remove the Ryujinx.HLE.OsHle.Handles namespace * Remove hbmenu automatic load on process exit * Rename Ns to Device, rename Os to System, rename SystemState to State * Move Exceptions and Utilities out of OsHle * Rename OsHle to HOS * Rename OsHle folder to HOS * IManagerDisplayService and ISystemDisplayService style fixes * BsdError shouldn't be public * Add a empty new line before using static * Remove unused file * Some style fixes on NPDM * Exit gracefully when the application is closed * Code style fixes on IGeneralService * Add 0x prefix on values printed as hex * Small improvements on finalization code * Move ProcessId and ThreadId out of AThreadState * Rename VFs to FileSystem * FsAccessHeader shouldn't be public. Also fix file names casing * More case changes on NPDM * Remove unused files * Move using to the correct place on NPDM * Use properties on KernelAccessControlMmio * Address PR feedback
