grep: reuse the first "util.binary()" result for efficiency
Before this patch, to check whether the file in the specified revision
is binary or not, "util.binary()" is invoked via internal function
"binary()" of "hg grep" once per a line of "hg grep" output, even
though binary-ness is not changed in the same file.
This patch reuses the first "util.binary()" invocation result by
annotating internal function "binary()" with "@util.cachefunc".
Performance improvement measured by "hgperf grep -r 88d8e568add1 vfs
