On Apple Silicon, when Hardened Runtime is in force and the
application lacks the "Allow Unsigned Executable Memory Entitlement",
mmap and mprotect return EACCES when an attempt is made to create or
modify memory so that it is simultaneously writable and executable.
This commit handles these cases by retrying the operation without the
PROT_EXEC flag, and setting global variables so that future operations
omit the flag.
Publish minor changes to readme and configure files in main directory.

* CONFIG_POLL_NONE (because the user-visible consequence is that polling is no longer supported; was CONFIG_PROTECTION_NONE).
* DISABLE_LOCKS (was THREAD_SINGLE).
* DISABLE_SHIELD (was THREAD_SINGLE && PROTECTION_NONE)
* DISABLE_REMEMBERED_SET (was PROTECTION_NONE)
When the shield is disabled, ArenaLeave asserts that there are no busy traces, and ArenaPoll is a no-op.
By having functions implemented using the corresponding macro, we can avoid duplicated code, and avoid testing DISABLE_SHIELD in global.c.
Remove all remaining references to MPS_PROD_EPCORE.
