machine: refactor PWM support
...
This commit refactors PWM support in the machine package to be more
flexible. The new API can be used to produce tones at a specific
frequency and control servos in a portable way, by abstracting over
counter widths and prescalers.

machine: make machine.I2C0 and similar objects pointers
...
This makes it possible to assign I2C objects (machine.I2C0,
machine.I2C1, etc.) without needing to take a pointer.
This is important especially in the future when I2C may be driven using
DMA and the machine.I2C type needs to store some state.

machine: move errors.New calls to globals
...
Calling errors.New in an error path causes a heap allocation at an
already unfortunate moment. It is more efficient to create these error
values in globals and return these constant globals. If these errors are
not used (because the related code was optimized out), the globals will
also be optimized out.

machine: avoid binary size regression after LLVM memory intrinsics
...
Somehow moving to LLVM memory intrinsics for calls like memcpy made the
machine.sendUSBPacket get inlined. This is a problem because it is
called in many different functions and it is just big enough to cause a
significant file size increase.
Adding //go:noinline solves this problem and gets the examples/blinky1
program below the file size it was before this change (tested:
itsybitsy-m0, itsybitsy-m4, circuitplay-bluefruit).

all: add compiler support for interrupts
...
This commit lets the compiler know about interrupts and allows
optimizations to be performed based on that: interrupts are eliminated
when they appear to be unused in a program. This is done with a new
pseudo-call (runtime/interrupt.New) that is treated specially by the
compiler.

machine: rename CPU_FREQUENCY -> CPUFrequency()
...
These all-caps constants aren't in the Go style, so rename it to
CPUFrequency (which is more aligned with Go style). Additionally, make
it a function so that it is possible to add support for changing the
frequency in the future.
Tested by running `make smoketest`. None of the outputs did change.

allow the pins to be set using machine.I2CConfig. This will also
