/** Determine accessibility of a file.
The access() function checks the file, named by the pathname pointed to by
the Path argument, for accessibility according to the bit pattern contained
in Mode.
The value of Mode is either the bitwise-inclusive OR of the access
permissions to be checked (R_OK, W_OK, X_OK) or the existence test (F_OK).
If Path ends in '/' or '\\', the target must be a directory, otherwise it doesn't matter.
A file is executable if it is NOT a directory and it ends in ".efi".
@param[in] Path Path or name of the file to be checked.
@param[in] Mode Access permissions to check for.
@retval 0 Successful completion.
@retval -1 File is not accessible with the given Mode. The error condition
is indicated by errno. Values of errno specific to the access
function include: EACCES, ENOENT, ENOTDIR, ENAMETOOLONG
