fix(fs): carry file_get_contents results as bytes

file_get_contents() and file_get_contents_with_max_length() return
Vec<u8> instead of a from_utf8_lossy'd String.
Call sites whose consumer takes a &str still convert lossily and are
marked TODO(bytes).

file_get_contents_with_max_length() now reads at most the requested
number of bytes instead of the whole file.
