new 7eb9bb0be6e cmake: Omit default priority ELF symbol.

cmake: Omit default priority ELF symbol.
nuttx_add_application() encoded SCHED_PRIORITY_DEFAULT as a zero-valued
nx_priority linker symbol. A zero priority is invalid for a runnable ELF
application task.
Do not emit nx_priority for the symbolic default. When the symbol is
absent, the ELF loader retains its scheduler default. Continue emitting
nx_priority for explicit numeric priorities.
Companion to apache/nuttx-apps#3667.
