Don't stress 'remote' in "Data Caching" in doc

When I try to describe the cache and its related commands (in a
cache-per-address-space world), I find hard to add, because
existing doc is focused on remote debugging, while data cache is used
regardless of the target.  More precisely, GDB cache target data,
instead of remote data.

gdb/doc:
