Eli Lipsitz da48a52d7a Fix File::readString to work with binary data (#8742) ...

Previously, File::readString used a C-style string as an intermediate
buffer via the String += operator. This treats a NUL byte as a
terminator, making this function work incorrectly if the File contains
binary data.

This commit switches the function to use String::concat, which doesn't
treat NUL bytes any differently (and is a bit faster, because it doesn't
need to use strlen).
