Summary [JSC] Allow fixedExecutableMemoryPoolSize to be set during build

Currently the memory pool size is set based on the CPU. The x64 version uses a 1GB pool size by default which is very large value. This value should be able to be specified by the port to allow overriding of the defaults.

Created attachment 289715 [details] Add macro This allows the size in MB to be specified by the port. In CMake you would use add_definitions(-DFIXED_EXECUTABLE_MEMORY_POOL_SIZE_IN_MB=<value>) within the Platform cmake file within JavaScriptCore. I'm open to changes to the name and also not sure if there should be any sort of static assert that ensures the validity of the value.
