Subject: [PATCH] Define default RE2C_FLAGS (#14615)

The --no-generation-date flag is a common re2c flag used in all re2c
invocations. This adds the 2nd optional argument to PHP_PROG_RE2C M4
macro in BC manner to set the default re2c command-line options and sets
the default RE2C_FLAGS similarly on Windows.
