Reland "Remove CapsMap from IR Generator."

This reverts commit 45c57e116ee0ce214bdf78405a4762722e4507d9.

Reason for revert: removing static constructor

Original change's description:
> Revert "Remove CapsMap from IR Generator."
>
> This reverts commit 6394bb43cbb5f7fc611bbca5440750c282d0cd76.

> Reason for revert: chrome roll still,
>
> Dumping static initializers via dump-static-initializers.py:
> #  SkSL::CapsLookupTable::CapsLookupTable(std::initializer_list<std::__1::pair<char const*, SkSL::CapsLookupMethod*> >)
>
>
> Original change's description:
> > Remove CapsMap from IR Generator.
> >
> > Previously, the IRGenerator's fCapsMap was a lookup table from caps-name
> > to caps-value.
> >
> > This has been replaced with a lookup table from caps-name to
> > caps-lookup-method. This is more general-purpose; you can initialize it
> > once and it always works, instead of needing to initialize it based on
> > a static set of caps.
> >
> > The next step after this CL is to migrate this logic into Settings and
> > remove caps handling from the IR Generator entirely.
