boot/net: rename Boot.S files, clarify EEPROM implication, and prep UDP read

- Renamed Boot.S → BootNetStartup.S and SysChk/Boot.S → SysChkStartup.S for clarity
- Replaced BOOTNET_INTERNET_HEADER.ImpliesEEPROM with ImpliesProgram to better reflect the generic reprogramming intent
- Introduced `bootnet_read_udp_packet()` stub for future UDP packet parsing from bootnet.json
- Minor alignment and comment fixes in various headers (CoreBoot, EPM, Json)
- Updated HalPagingMgr to use PageStore instead of NE_PAGE_STORE
- Boot time now prints cycles since start; triggered fs_init_nefs() earlier during HAL init
- Prep for extended MBCI and master structure support in COREBOOT_LINEAR_EXEC
- Numerous cleanups across DMA, NewKit, and Json parsing to prep for extended patching and block-level bootstrap

This lays groundwork for richer NetBoot infrastructure in NeKernel and aligns naming and structure conventions across subsystems.
