platform: generic: Optimize extensions_init() to parse ISA extensions once

Instead of parsing ISA extensions separately for each hart in the
generic_extensions_init() function, it is better to parse ISA extensions
for all available harts in the cold boot path. Also, this allows us
to remove fdt_isa_bitmap from scratch space and directly initialize
"extensions" in struct sbi_hart_features for each hart.
