Code Modernization: Use file_get_contents() in wp_get_webp_info().

file_get_contents() is faster than fread(), because the PHP core can decide how to best read the remaining file; it could decide to issue just one read() call or mmap() the file first.

Per the PHP manual, file_get_contents() or stream_get_contents() is the preferred way to read the contents of a file into a string. It will use memory mapping techniques if supported by the OS to enhance performance.

Reference: PHP Manual: file_get_contents().

Follow-up to [50810], [52696], [52698], [52701].
