Lucas De Marchi c9dfd66cb9 drm/xe/lrc: Allow INDIRECT_CTX for more engine classes
Currently it's only allowed for render and compute. Going forward we
want to enable it for more engine classes. Let the XE_LRC_FLAG_INDIRECT_CTX
flag (and thus gt_engine_needs_indirect_ctx()) be the deciding factor
for its availability.

While at it, add the missing const to rcs_funcs array. Since
CTX_INDIRECT_CTX_OFFSET_DEFAULT already matches the HW default and
gt_engine_needs_indirect_ctx() only ever enables it for rcs/ccs, there
is no change in behavior, it's only preparation for future use case.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
