RISC OS Javascript support

Thanks to Rob Kendrik, Chris Gransden and myself we now have NSPR and
Spidermonkey libraries building in the NetSurf toolchain[1]. The CI
system[1] has built the toolchain successfully and a copy of NetSurf
for RISC OS with Javascript enabled[3].

I would be grateful if any interested users could test this build.

The javascript support is still *very* limited and the performance is
unlikely to be awe inspiring, please do not expect a great
experience. I still have a *lot* of interfaces remaining to implement
and we are a small development team lacking an active RISC OS
maintainer.

*** Please Note ***

All the usual caveats of using a CI build apply, additionally, this is
the first successful *experimental* build with these libraries. I have
been personally unable to test on RISC OS. It might fail in all sorts
of interesting (Chinese proverb style) ways and I cannot offer support
if it does.
