Although this makes some places more complicated, code should generally
be simpler and clearer. It could slightly improve performance on x64 for
functions with more than four parameters, since it makes more data be
passed via registers rather than the stack.

By changing signature of those two functions, we make compiler complain about
all their existing uses, so we can find all of them and convert them.
Some of the callsites of Get() with those properties are also converted, but not
all of them. It is fine because if there is any incorrect conversion, compilers
is able to find out now. So they are completely typesafe.

This patch makes methods of FramePropertyTable and FrameProperties to be
simple template wrapper functions. Then it converts all references to
FramePropertyDescriptor to use "void" parameter to simulate the current
unsafe behavior.
SmallValueHolder is used for storing small values like int32_t, float,
which can fit in the size of a pointer directly, and thus no lifetime
management is needed.

AutoTextRun now only needs a DrawTarget instead of an nsRenderingContext, and
similar nsRenderingContext/gfxContext-to-DrawTarget replacements can be
propagated a long way up the call graph. This patch replaces 93 occurrences of
nsRenderingContext and 135 occurrences of gfxContext with DrawTarget; that's
13% of them.
The patch is mostly plumbing changes. A couple of not-entirely-plumbing
changes:
- It adds a comment about the null check in
gfxGlyphExtents::GetTightGlyphExtentsAppUnits().
- A couple of functions simply had an unused gfxContext or nsRenderingContext
parameter removed, e.g. SetLineBreaks().

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
