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.
