clang-format: [JS] strict prop init annotation.
Summary:
TypeScript uses the `!` token for strict property initialization
assertions, as in:
class X {
strictPropAsserted!: string;
}
Previously, clang-format would wrap between the `!` and the `:` for
overly long lines. This patch fixes that by generally preventing the
wrap in that location.
