std::string unfortunately does not have a `string + string_view`
plus operator. (https://stackoverflow.com/q/44636549/291737)
This brings SkSL::String one step closer to matching std::string's API.

std::string is less permissive than SkSL::String about concatenation.
This change is a step towards eliminating SkSL::String.
(We couldn't continue using this technique for std::string, as it's
undefined behavior to add our own methods inside namespace std.)

Other than the `float`/`double` overloads, the only value-add of these
methods is to cast the result of `std::to_string` to `SkSL::String`.
When `SkSL::String` is removed, these no-op calls can be replaced with
direct calls to `std::to_string` instead. (The float overloads can
continue to live in `skstd` since their output isn't the same.)

This will make it easier to migrate from SkSL::String to std::string.
These methods can then continue to exist as free functions.

std::string::starts_with will be available in C++20. In the interim,
prefer using a free function in skstd. This puts us a small step closer
towards removing SkSL::String.

An API like this was never adopted in std::string. (The concept was
borrowed from absl::ConsumeSuffix.)
This is a step towards removing SkSL::String entirely, since we no
longer have a pressing need for it now that std::string_view and
std::string are compatible.

Because SkSL is much more permissive than GLSL about literal types, we
don't actually need to treat values any differently when the `u` suffix
is added. That is, `uint x = 4000000000;` already worked fine. When we
encounter the `u`, we just ignore it. This also means that a literal
like `-100u` would be accepted without complaint (although you'd get a
range error if you tried `uint x = -100u;`).
The value-add here is that it removes a speed bump when porting GLSL
code to SkSL. The Filament example shader used the `u` suffix anywhere
that bitwise ops were present; finding and removing all of them was a
chore.
Also of note: the `u` suffix was only added to GLSL in ES3, but we
"support" it everywhere. (We could go out of our way to detect it in
ES2 and flag an error, but that benefits no one.)
