lib: Add ASan support to romstage on x86 arch
This patch adds ASan support to romstage on x86 architecture. A Kconfig option is added to enable ASan in romstage. Compiler flags are updated. A memory space representing the shadow region is reserved in linker section. And a function call to asan_init() is added to initialize shadow region when romstage loads.
