strconv: clean up powers-of-10 table, tests Both Eisel-Lemire and Ryu depend on a table of truncated 128-bit mantissas of powers of 10, and so will Dragonbox. This CL: - Moves the table to a separate file, so it doesn't look tied to Eisel-Lemire. - Introduces a uint128 type in math.go for the table values, since .Hi and .Lo are clearer than [1] and [0]. - Generates the table from a standalone generator pow10gen.go. - Adds a new pow10 function in math.go to handle table access details. - Factors a 64x128->192-bit multiply into umul192 in math.go. - Moves multiplication by log₁₀ 2 and log₂ 10 into math.go. - Introduces an import_test.go to avoid having to type differently cased names in test code versus regular code. - Introduces named constants for the floating-point size parameters. Previously these were only in the floatInfo global variables. - Changes the BenchmarkAppendUintVarlen subtest names to be more useful.

strconv: move all but Quote to internal/strconv This will let low-level things depend on the canonical routines, even for floating-point printing.
