J. Nick Koston 062f223876 [json, core] Remove stored RAMAllocator, make constructors constexpr
RAMAllocator with default flags is stateless — it's just a dispatch
wrapper over heap_caps_malloc/realloc/free. Remove the stored member
from SpiRamAllocator, using stack-local instances at each call site.

Also make RAMAllocator constructors constexpr so the compiler can
fully evaluate flag logic at compile time.

Note: SpiRamAllocator was initialized with RAMAllocator::NONE (0),
which is equivalent to default construction since the constructor
preserves the default ALLOC_INTERNAL | ALLOC_EXTERNAL flags when
no valid allocation flags are provided.
